CHROMOPHORE COMPOUND AND PREPARATION METHOD THEREFOR, AND APPLICATION OF CHROMOPHORE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2023/231529
Kind Code:
A1
Abstract:
The present application provides a chromophore compound. The structure of the chromophore compound is as shown in formula (Ⅰ), wherein D is an atom capable of providing an electron, A is an electron acceptor group, B is an electron bridge group, Z, L1 and L2 are each independently selected from atoms or organic groups capable of forming at least two chemical bonds, X1 is a first cross-linkable group, X2 is a second cross-linkable group, and n, m, p and q are respectively integers greater than or equal to 1. The present application also provides a preparation method for the chromophore compound, an electro-optic material to which the chromophore compound is applied, a film, electro-optic glass, an electro-optic device, and an electronic device. According to the chromophore compound, an electron donor group having a strong power supply capability and a tetrahydroquinoline-like structure is introduced, and the first cross-linkable group and the second cross-linkable group are also introduced, such that the first-order hyperpolarizability, the electro-optic coefficient and the glass transition temperature of the chromophore compound are increased.
