Problems solved by technology

Using organic heterostructures formed by different molecules is difficult to ensure that different molecules can grow in a structure with a low lattice mismatch rate. In addition, the phase separation phenomenon during the growth process is also a major challenge in the preparation of organic heterojunctions. (Nano Lett. 2017, (17), 695)

Embodiment 1

[0040] In the following examples of the present invention, polycrystalline phase molecules select 3,3 '-((1E, 1'E)-蒽 -9,10-two-basis double (ethane-2,1-two-basis)) Aya (M-B 2 BCB), the structure is as follows:

[0041]

[0042] The preparation method of this compound is: first mixing 9,10-two (chlorotripotramel) 蒽 (15g, 0.05 mol) with trigly acetic acid (18g, 0.10 mol) in the round bottom bottle, and the reaction mixture is 150 ℃ Mix the product for 4 hours to dry the product and get the intermediate product four ethyl-9,10-two-yamya-based two-膦 膦 acid salt. After that, the four ethyl-9,10-two-ya-methyl-based macaride (0.9g, 1.91mmol) and 3-cyanophenzide (0.5g, 3.81mmol) were dissolved in the cool tetrahydrofura (70ml). Essence Sodium sodium sodium (0.7g, 7.62 mmol) is added to the tetrahydrofurant solution stored at room temperature. The reaction mixture is stirred at room temperature for 4h, poured into the water, and the organic phase is extracted with dichloromethane. The mi...

Embodiment 2

[0055] By using the same method as Example 1, the same intermediate product four-ethyl-9,10-ertami methyl (0.9g, 1.91mmol) and 2-cyanophenzide (0.5g , 3.81mmol) dissolved in the cooling tetrahydrofurate (70ml). Sodium sodium sodium (0.7g, 7.62 mmol) is added to the tetrahydrofurant solution stored at room temperature. The reaction mixture is stirred at room temperature for 4h, poured into the water, and the organic phase is extracted with dichloromethane. The mixed organic phase was washed with water, dried, filtered, and evaporated on the waterless mgso4. Use dichloromethane / petroleum ether (3: 1) to separate the chromatography on the silicone. Finally, compounds obtained with high fluorescent orange powder (O-B 2 BCB) (0.29g, 0.67mmol), the yield is 58 %. The structure is as follows:

[0056]

[0057] Use two bad solvents to test, and 10.23mg O-B 2 Add BCB to 10ml of dichloromethane to obtain a dichloroethane reserve liquid, and then add the obtained dichloro methane reserve t...

Abstract

The invention relates to an organic heterogeneous micro-nano crystal based on polycrystalline phase molecules. The organic heterogeneous micro-nano crystal consists of one polycrystalline phase molecule, and the polycrystalline phase molecule in the organic heterogeneous micro-nano crystal has at least two crystal phase, and a heterostructure is formed between the crystalline phases. The preparation method of the organic heterogeneous micro-nano crystal of the invention is convenient and simple, and the method broadens the molecular material system of the organic heterojunction and the thinking of the preparation method.

Description

Technical field [0001] The present invention involves the field of optoelectric components and is especially involved an organic heresy micr -nano crystal based on polycrystalline phase molecules and its preparation and application. Background technique [0002] In recent years, with the demand for high -performance photoelectric equipment, such as field effects crystal pipes, light wave guide devices and light -emitting diode (Nat Nanotechnol.2010, (5), 225) You can integrate multiple components into one structure to overcome the challenges of a single output channel, providing more feasibility for achieving more transmission modes (AngeewChemint ED.2017, (56), 3616). In addition, the organic heterogeneous structure itself also has a series of advantages such as simple preparation and synthesis, flexible molecular structure design, and spectral spectral adjustment. Therefore, in order to create multi -functional and high -performance photoelectronic devices, such as photon route...
