Problems solved by technology

Generally speaking, linear polymer materials are easy to prepare, and the cost is relatively low, but its nonlinear optical effect is difficult to achieve high indicators; and the nonlinear optical properties of dendrimers can achieve better results, but Its preparation is cumbersome, the separation and purification of each generation of molecules is quite difficult, and it is difficult for multi-generation polymers to achieve a regular structure.

Embodiment 1

[0017] When R is a nitro group, the synthetic route is as follows:

[0018]

[0019]

[0020] The synthesis method is:

[0021] (1) Synthesis of compound 3

[0022] Add p-nitroaniline 2 to 35% aqueous solution of concentrated hydrochloric acid (the quality of water is 3 times that of concentrated hydrochloric acid), wherein the quality of concentrated hydrochloric acid is 2.5 times that of p-nitroaniline 2, and vigorously stir. Under an ice bath, slowly drop an aqueous solution of sodium nitrite into the reaction liquid, wherein the mass percent concentration of sodium nitrite is 10%-20%, keep stirring at 0° C. for 15 minutes, and then filter to remove insoluble matter. Dissolve compound 1 in appropriate ethanol and slowly add it dropwise to the vigorously stirred filtrate. After the dropwise addition, keep stirring at 0°C for 1 hour, add sodium bicarbonate to adjust the pH value to 7, and continue stirring at room temperature for half an hour. Filter and wash the filt...

Embodiment 2

[0034] When R is a sulfone group, the synthetic route is as follows:

[0035]

[0036] The synthesis method is:

[0037] (1) Synthesis of Compound 8

[0038] Add p-ethylsulfoneaniline 7 to 35% aqueous solution of concentrated hydrochloric acid (the quality of water is 3 times that of concentrated hydrochloric acid), wherein the quality of concentrated hydrochloric acid is 2.5 times that of p-ethylsulfoneaniline 7, and vigorously stir . Under an ice bath, slowly add an aqueous solution of sodium nitrite dropwise to the reaction liquid, wherein the mass percent concentration of sodium nitrite is 10%-20%, keep stirring at 0° C. for 15 minutes, and then filter to remove insoluble matter.

Description

technical field [0001] The invention relates to a novel hyperbranched second-order nonlinear optical polymer, its preparation method and application. Background technique [0002] The development of science and technology is changing with each passing day, and the pursuit of human beings is also endless. At present, relying on the development of electronics and microelectronics technology, human beings have established a fairly complete and systematic information network. However, with the progress of society, the existing information systems still cannot meet human's requirements for fast and accurate information processing, transmission, and transformation. At the same time, due to the physical limit of the electron itself, mainly as the transmission speed limit of the information carrier and the density limit of the information storage, the potential of the electron in information is almost exhausted. In contrast, photons, as carriers of information, have just debuted. ...
