Abstract

The invention relates to a compound having a D-pi-A structure as well as a preparation method and application of the compound. The method uses an indacene derivative as a pi-conjugated electron bridge, and introduces an electron-donating group and an electron-withdrawing group at two ends of the derivative to prepare the nonlinear optical chromophore having the D-pi-A structure. The longer conjugation length of the chromophore makes the chromophore have larger first-order hyperpolarizability (beta), so that high-performance organic electrooptical materials can be prepared. The chromophore provided by the invention has a larger molecular weight, in addition to be doped with a polymer to prepare a film, the chromophore can be directly dissolved by using an organic solvent and used to preparea film through spin coating, and the chromophore provides great convenience for a componentization process; and the chromophore provided by the invention also has a higher thermal decomposition temperature and glass transition temperature, so that nonlinear optical chromophore molecules have extremely good orientation stability in materials, and meet requirements for componentization to a large extent.

Description

technical field [0001] The invention relates to the field of organic second-order nonlinear optical materials, in particular to an organic second-order nonlinear chromophore with D-π-A structure based on indacene derivatives with higher thermal decomposition temperature and orientation stability preparation methods and applications. Background technique [0002] As the important material basis of laser technology and communication technology, nonlinear optical materials have become a hot spot in current technology research. Nonlinear optical materials have important applications in the fields of optical information processing, high-speed optical communication, optoelectronics and integrated circuits. As we all know, the switching speed of photons is several orders of magnitude faster than that of electronic processes, so working at optical frequencies can greatly increase the bandwidth of information processing, and the use of harmonic generation, parametric oscillation and...
