Problems solved by technology

In the field of optical storage, one of the key problems in the application of polymer nonlinear optical materials is that their absorption wavelength is in the ultraviolet region, and laser light sources in the ultraviolet region are expensive and cannot be widely used
Another problem is that the thermal stability of polymer materials is not high, which is not ideal in terms of storage time and fatigue resistance.
[0003] The usual method is to use a rigid backbone to increase the glass transition ...

Abstract

The present invention belongs to the field of photoelectronic functional material technology, and is especially one kind of optical active organic chromophore molecule of azometaphenylene diamine and its synthesis process. The present invention features that the azometaphenylene diamine compound is synthesized with metaphenylene diamine and aromatic diazo salt and through coupling reaction, has absorption wavelength in the visible light area, and possesses two reaction active primary amine groups. The azometaphenylene diamine compound may be mixed with polymer to obtain non-linear optical performance and may be reacted with diisocyanate and other active monomer to introduce polymer chain, so as to obtain polymer with high chromophore content, excellent heat stability, etc. It may be used in preparing light memory medium with high storing density and high stability.

Description

technical field [0001] The invention belongs to the technical field of photoelectric functional materials, and in particular relates to an azobenzene optically active organic chromophore molecule and a preparation method thereof. Background technique [0002] In the field of optics for more than ten years, the research of optical storage media with high storage density and high stability has attracted extensive attention. The excellent optical transparency, film-forming properties and molecular designability of polymers make them a research hotspot in both aspects, but both face some urgent problems to be solved. In the field of optical storage, one of the key problems in the application of polymer nonlinear optical materials is that their absorption wavelength is in the ultraviolet region, and laser light sources in the ultraviolet region are expensive and cannot be widely used. Another problem is that the thermal stability of polymer materials is not high, which is not id...
