Background Art
[0002] Logic gates are fundamental digital circuit elements used to perform logical operations. They typically consist of multiple inputs and a single output, whose output state depends on the logic state of the input signals. Different types of logic gates can perform different logical operations, such as AND, OR, NOT, and XOR. Logic gates play a crucial role in digital electronic circuits, enabling the implementation of a variety of digital logic circuits, such as computers, communications systems, and control systems. They are the foundation of digital electronic technology.
[0003] Molecular logic gates that modulate fluorescence intensity have been reported. While logic systems based on fluorescence intensity have been developed, they lack diversity and spatiotemporal complexity. While the use of fluorescence signals and changes as dynamic demonstration and imaging techniques has garnered significant attention, logic gates based on fluorescence still require further design and optimization. Some studies aimed at modulating fluorescence have encountered challenges, such as irreversibility and monotonic fluorescence changes. These issues urgently need to be addressed, particularly given the adverse effects of monotonic fluorescence changes on information transmission. Summary of the Invention

[0015] Furthermore, the fluorescent dye is disodium distyryl diphenyl disulfonate, eosin Y or sulforhodamine B.
[0016] Furthermore, the acidic water is prepared by adjusting the pH of the water with hydrochloric acid, because the sulfonic acid merocyanine will be ineffective under alkaline conditions, and it is difficult to have a very good effect under very low acidic conditions, so the pH of the acidic water is selected to be 4-6.
[0017] Furthermore, when the surfactant is dodecyltrimethylammonium chloride, the concentration of the surfactant in the light-controlled dissipative self-assembly system is 0.75-1.25 mmol / L, and the concentration of the sulfonic acid merocyanine is 0.12-0.16 mmol / L.

[0021] The present invention also includes a reversible logic gate of light-controlled dissipative self-assembly loaded with fluorescent molecules, and the reversible logic gate includes the light-controlled dissipative self-assembly dynamic luminescence system of the present invention as a light-controlled dissipative system.
[0022] Furthermore, the reversible logic gate is an AND gate, an XNOR gate, or an XOR gate.
[0023] Furthermore, the reversible logic gate is a dual-input single-output mechanism, where input A is 420±10nm light irradiation or dark conditions, input B is various excitation lights or surfactants, and output C is the intensity of fluorescence change.
[0024] Furthermore, when it is an AND gate, the system obtained by adding the fluorescent dye disodium distyryl diphenyl disulfonate into the light-controlled dissipative self-assembly system of the surfactant dodecyltrimethylammonium chloride and sulfonic acid merocyanine is used as the light-controlled dissipative system, the input A is dark conditions or 420±10nm light irradiation, the input B is dark or 350±20nm light irradiation, and the output C is the strength of the fluorescence intensity of 440±10nm.
[0025] Furthermore, when it is an exclusive-NOR gate XNOR, the system obtained by adding the fluorescent dye Eosin Y into the light-controlled dissipative self-assembly system of the surfactant hexadecyltrimethylammonium chloride and sulfonic acid merocyanine or the light-controlled dissipative self-assembly system of the surfactant dodecyltrimethylammonium chloride and sulfonic acid merocyanine is used as the light-controlled dissipative system, the input A is darkness or 420±10nm light irradiation, the input B is the surfactant dodecyltrimethylammonium chloride or the surfactant hexadecyltrimethylammonium chloride, and the output C is the strength of the fluorescence intensity at 550±10nm.
[0026] Furthermore, when it is gate XOR, the system obtained by adding the fluorescent dye sulfonylrhodamine B into the light-controlled dissipative self-assembly system of the surfactant tetradecyltrimethylammonium chloride and sulfonic acid merocyanine is used as a light-controlled dissipative system, the input A is darkness or 420±10nm light irradiation, the input B is 365±10nm or 570±10nm light irradiation, and the output C is the strength of the fluorescence intensity of 590±10nm.
[0027] The application of the light-controlled dissipative self-assembled dynamic luminescence system or the reversible logic gate described in the present invention in information transmission and storage.
[0028] The present invention is based on the interaction between the light-responsive molecule sulfonic acid merocyanine and a series of cationic surfactants to form a light-dissipative self-assembly system, which is then loaded with a fluorescent dye to obtain a light-controlled dissipative self-assembled dynamic luminescence system. Sulfonic acid merocyanine can be photoisomerized to a spiropyran structure at 420±10nm, and then assembled with a surfactant in an acidic aqueous solution at room temperature into spherical nanoparticles, i.e., a light-controlled dissipative self-assembly system. At the same time, this type of light-controlled dissipative self-assembly system can achieve different dynamic changes in fluorescence by loading different fluorescent dyes. On this basis, a series of logic signal gates that achieve dynamic changes in fluorescence based on different inputs have been developed. The preparation routes of the various light-controlled dissipative self-assembled dynamic luminescence systems in the present invention are simple, and the dynamic changes in fluorescence only need to be achieved by changing the dynamic luminescence system or changing the wavelength of the excitation light and used as the design basis for the logic signal. It has great application potential in the fields of information transmission and information storage such as molecular computing and sensing.

These systems, as exemplary examples of fluorescence-dependent logic gates, lay the foundation for solving information transmission problems and for applications in organic systems with logic signals. They simplify basic logic gate designs within existing logic gates, enrich the application of organic systems in fluorescence logic gates, and optimize the reciprocity and non-monotonicity of fluorescence changes in the development of fluorescence logic gates.

[0042] The technical solution of the present invention is further described below with reference to the accompanying drawings. 1 μL of 1 mol / L hydrochloric acid is added to 25 mL of neutral water to adjust the pH of the water to obtain acidic water with a pH of 5.6-5.7;
[0043] A 0.5 mmol / L sulfonic acid merocyanine solution was prepared as the mother solution for subsequent experiments;
[0044] Example 1
[0045] The sulfonic acid merocyanine solid dispersion was dissolved in acidic water, and ultrasonic dissolution was performed to obtain concentrations of 0 mmol / L, 0.02 mmol / L, 0.04 mmol / L, 0.06 mmol / L, 0.08 mmol / L, 0.10 mmol / L, 0.12 mmol / L, 0.14 mmol / L and 0.16 mmol / L, respectively. The surfactant dodecyltrimethylammonium chloride was added and mixed thoroughly, and the concentration of dodecyltrimethylammonium chloride in the system was fixed at 1 mmol / L to obtain nine groups of light-controlled dissipative self-assembly systems.
[0046] The optical transmittance of the nine groups of light-controlled dissipative self-assembly systems at 650 nm was measured after irradiation with 420 nm light for 150 s. Figure 1 shown. Figure 1 To fix the concentration of dodecyltrimethylammonium chloride at 1mmol / L, the concentration of sulfonic acid merocyanine solution gradually increased from 0 to 0.16mmol / L. Figure 1 It can be seen that the concentration of sulfonic acid merocyanine gradually decreases with the increase of the concentration of sulfonic acid merocyanine, so on this basis, the concentration of sulfonic acid merocyanine solution was selected to be 0.14mmol / L for subsequent exploration experiments. Among them, the structural formula of dodecyltrimethylammonium chloride is shown in Formula II.
[0047]
[0048] Example 2
[0049] The preparation process of the light-controlled dissipative self-assembly system is the same as that in Example 1, wherein the concentration of the fixed sulfonic acid merocyanine is 0.14 mmol / L, and the concentrations of dodecyltrimethylammonium chloride are 0 mmol / L, 0.25 mmol / L, 0.5 mmol / L, 0.75 mmol / L, 1.0 mmol / L, 1.25 mmol / L, 1.5 mmol / L, 2.0 mmol / L, 2.5 mmol / L, and 3.0 mmol / L, respectively, to obtain ten groups of light-controlled dissipative self-assembly systems.
[0050] The optical transmittance of the ten light-controlled dissipative self-assembly systems was also measured at 650 nm after irradiation with 420 nm light for 150 s. Figure 2 shown. Figure 2 The UV transmission titration diagram of the fixed concentration of sulfonic acid merocyanine at 0.14mmol / L and the concentration of dodecyltrimethylammonium chloride gradually increasing from 0 to 3mmol / L is shown in the figure. Figure 2 It can be seen that the lowest point of optical transmittance appeared when the concentration of dodecyltrimethylammonium chloride was 1 mmol / L, indicating that the optimal assembly concentration was dodecyltrimethylammonium chloride 1 mmol / L / merocyanine sulfonate 0.14 mmol / L.
[0051] The spherical nanoparticles formed by irradiating the sulfonic acid merocyanine and dodecyltrimethylammonium chloride obtained by the optimal assembly concentration of dodecyltrimethylammonium chloride 1mmol / L / sulfonic acid merocyanine 0.14mmol / L in this example were analyzed by scanning electron microscopy and transmission electron microscopy. The results are as follows: Figure 7-8 As shown. Figure 7 This is a scanning electron micrograph of spherical nanoparticles formed by sulfonic acid merocyanine and dodecyltrimethylammonium chloride after irradiation; Figure 7 It can be seen that sulfonic acid cyanine and dodecyltrimethylammonium chloride form 80nm spherical nanoparticles after illumination. In the dark, sulfonic acid cyanine and dodecyltrimethylammonium chloride do not assemble, but after illumination, sulfonic acid cyanine isomerizes and dodecyltrimethylammonium chloride forms 80nm spherical nanoparticles.
[0052] Figure 8 This is a transmission electron microscopy image of spherical nanoparticles formed by sulfonic acid merocyanine and dodecyltrimethylammonium chloride after light exposure; Figure 8 It can be seen that dodecyltrimethylammonium chloride and sulfonic acid merocyanine successfully constructed a light-controlled dissipative self-assembly system before and after illumination.
[0053] Example 3
[0054] The preparation process of the light-controlled dissipative self-assembly system is the same as that in Example 1, wherein tetradecyltrimethylammonium chloride is used as the surfactant, the concentration of tetradecyltrimethylammonium chloride is fixed at 0.2 mmol / L, and the concentration of sulfonic acid merocyanine is gradually increased from 0 to 0.1 mmol / L, that is, 0 mmol / L, 0.01 mmol / L, 0.02 mmol / L, 0.03 mmol / L, 0.04 mmol / L, 0.05 mmol / L, 0.06 mmol / L, 0.07 mmol / L, 0.08 mmol / L, 0.09 mmol / L and 0.10 mmol / L, respectively, to obtain eleven groups of light-controlled dissipative self-assembly systems.
[0055] The above eleven groups of light-controlled dissipative self-assembly systems were also irradiated with 420nm light for 150s and the optical transmittance at 650nm was measured. The results are as follows: Figure 3 shown. Figure 3 The UV transmittance titration diagram of the sulfonic acid merocyanine concentration gradually increasing from 0 to 0.1 mmol / L when the concentration of tetradecyl trimethyl ammonium chloride is fixed at 0.2 mmol / L is obtained by Figure 3It can be seen that the optical transmittance gradually decreases with the increase of the sulfonic acid merocyanine concentration, but changes occur when the sulfonic acid merocyanine concentration is around 0.01mmol / L. When the optical transmittance increases from 0 to 0.01mmol / L, there is basically no change in the optical transmittance, while the rate of decrease of the optical transmittance at 650nm increases significantly from 0.01 to 0.1mmol / L. Therefore, the sulfonic acid merocyanine concentration is selected to be 0.1mmol / L. Among them, the structural formula of epitetradecyltrimethylammonium chloride is shown in Formula III,
[0056]
[0057] Example 4
[0058] The preparation process of the light-controlled dissipative self-assembly system is the same as that in Example 1, wherein the concentration of sulfonic acid merocyanine is fixed at 0.1 mmol / L, and the concentration of tetradecyltrimethylammonium chloride is increased from 0 to 0.5 mmol / L, i.e., 0 mmol / L, 0.05 mmol / L, 0.1 mmol / L, 0.15 mmol / L, 0.2 mmol / L, 0.25 mmol / L, 0.3 mmol / L, 0.35 mmol / L, 0.4 mmol / L, 0.45 mmol / L and 0.5 mmol / L, respectively, to obtain eleven groups of light-controlled dissipative self-assembly systems.
[0059] The above eleven groups of light-controlled dissipative self-assembly systems were also irradiated with 420nm light for 150s and the optical transmittance at 650nm was measured. The results are as follows: Figure 4 shown. Figure 4 The UV transmission titration diagram of the fixed concentration of sulfonic acid merocyanine at 0.1mmol / L and the concentration of tetradecyltrimethylammonium chloride gradually increasing from 0 to 0.5mmol / L is shown in the figure. Figure 4 It can be seen that the optical transmittance at 650 nm is lowest at a concentration of 0.2 mmol / L of tetradecyltrimethylammonium chloride, ranging from 86–88%, which is consistent with the previous experimental results with an error of no more than 2%, indicating that the optimal assembly concentration is 0.2 mmol / L of tetradecyltrimethylammonium chloride / 0.1 mmol / L of sulfonic acid merocyanine.

[0062] The above eleven groups of light-controlled dissipative self-assembly systems were also irradiated with 420nm light for 150s and the optical transmittance at 650nm was measured. The results are as follows: Figure 5 shown. Figure 5 The UV transmittance titration diagram of the sulfonic acid merocyanine concentration gradually increasing from 0 to 0.1 mmol / L when the concentration of hexadecyltrimethylammonium chloride is fixed at 0.04 mmol / L is obtained by Figure 5 It can be seen that the optical transmittance at 650nm gradually decreases with the increase of the concentration of sulfonic acid merocyanine, but changes when the concentration of sulfonic acid merocyanine is about 0.04mmol / L. Therefore, the optimal concentration of sulfonic acid merocyanine is selected as 0.09mmol / L. Among them, the structural formula of hexadecyltrimethylammonium chloride is shown in Formula IV.
[0063]

Figure 6 The UV transmittance titration diagram of the fixed concentration of sulfonic acid merocyanine at 0.09mmol / L and the concentration of hexadecyltrimethylammonium chloride gradually increasing from 0 to 0.08mmol / L is shown in the figure. Figure 6It can be seen that the lowest point of the optical transmittance at 650 nm appeared at 0.04 mmol / L of hexadecyltrimethylammonium chloride, indicating that the optimal assembly concentration is 0.04 mmol / L of hexadecyltrimethylammonium chloride and 0.09 mmol / L of sulfonic acid merocyanine.

[0083] The above-mentioned dynamic luminescence system of light-controlled dissipative self-assembly is used to prepare a reversible logic gate, wherein the input A is darkness 0 or 420±10nm light irradiation 1, the input B is 365±10nm light irradiation 0 and 570±10nm light irradiation 1, and the output C is 590±10nm fluorescence intensity weak 0 and fluorescence intensity strong 1, respectively. Figure 11 As shown, a reversible logic signal gate XOR gate among the logic signal gates of light-controlled dissipative self-assembly loaded fluorescent molecules is obtained.
[0084] Figure 11 Design of an XOR logic gate, which includes 0.02mmol / L of the fluorescent dye sulfonylrhodamine B, and the dynamic change diagram of 590nm fluorescence under 365nm and 570nm excitation before and after 420nm light irradiation. Among them, A is an input-output schematic, which includes input A 420±10nm light irradiation or darkness and input A 365±10nm light irradiation or 570±10nm light irradiation, and the output is the fluorescence intensity of 590±10nm. B is a summary diagram, and C is a truth table and a schematic diagram of the dissipative self-assembly process of two input stimulus responses and output fluorescence intensity changes, that is, when input A is 1 and input B is 1, output C is 0; when input A is 0 and input B is 0, output C is 0; when input A is 0 and input B is 1, output C is 1; when input A is 1 and input B is 0, output C is 1, and when input A is 1 and input B is 0, output C is 1. Under irradiation, it stabilizes after 50s, the fluorescence intensity of 590±10nm is weak, and the output is 0; without irradiation of 420±10nm light and 570±10nm light, the fluorescence intensity of 590±10nm becomes stronger, and the output is 1; under irradiation of 420±10nm light and 365±10nm light, the fluorescence intensity of 590±10nm becomes stronger, and the output is 1; without irradiation of 420±10nm light and 365±10nm light, the fluorescence intensity of 590±10nm becomes weak, and the output is 0. Five cycles were performed, respectively. Figure 11 It can be seen that the reversible reciprocation of the logic gate XOR is successfully implemented.
