具有Y型的D-π-A结构的有机二阶非线性光学发色团及合成方法和用途
摘要：
本发明提供一种具有Y型的D‑π‑A结构的有机二阶非线性光学发色团，该具有Y型的D‑π‑A结构的有机二阶非线性光学发色团具有以下结构：其中，X为S或O原子；R1为甲基或三氟甲基；R2为烷基或苯基。本发明所使用的电子给体、共轭π电子桥和电子受体组合在一起后分子内电子传输能力增强，可以提高电光系数。另外，合成的发色团分子具有特殊Y型结构，能有效降低分子间相互作用力。将所述有机二阶非线性光学发色团与无定型聚碳酸酯掺杂用于合成聚合物薄膜，该聚合物薄膜可作为合成光信号调制材料使用。
摘要（英）：

The invention provides an organic second-order nonlinear optical chromophore having a Y-type D-pi-A structure. The organic second-order nonlinear optical chromophore having the Y-type D-pi-A structure has a structure as shown below in the specification, wherein X is an S or O atom; R1 is methyl or trifluoromethyl; and R2 is alkyl or phenyl. After an electron donor, a conjugate pi electron bridge and an electron acceptor, which are used by the invention, are combined together, the intramolecular electron transmission capability is enhanced, and the electrooptic coefficient can be increased. Besides, the synthesized chromophore molecule has the special Y-type structure, thereby effectively reducing the intermolecular interaction force. The organic second-order nonlinear optical chromophore is doped with amorphous polycarbonate to realize synthesis of a polymer film, and the polymer film can be used as a synthetic optical signal modulation material.
