项目摘要

Molecular design and syntheses of new polycyclic dithiines and quinoid dyes for 3rd order nonlinear optical materials were studied. These dyes have large pi-conjugated systems and intramolecular charge-transfer chromophoric systems. A wide and planar structure of dye molecule with strong intra-and intermolecular hydrogen bonding are very important to produce strong intermolecular pi-pi interactions of dye molecules in crystals or thin film for NLO devices. This system has large photoinduced polarization which is favorable for 3rd order NLO materials.On the other hand, intermolecular CT complexes composed of polycyclic dithiines with TCNQ were also synthesized and their NLO responses were evaluated.Some quinoid dyes produce three dimensional molecular stacking in crystals by interlayr pi-pi interactions which play a great role to produce a large CHI^<(3)> value. We found two types of new quinoid dyes, 4,8-dihydroxy-2,6-bis (butylamino) -1,5-naphthoquinone and 1,4-dithioketo-3,6-diphenylpyrrolo [3,4-c] pyrrole, which were one of the candidates for 3rd order NLO materials.

研究了用于三阶非线性光学材料的新型多环二硫杂环和喹啉类染料的分子设计和合成。这些染料具有大的pi共轭体系和分子内电荷转移发色体系。具有分子内和分子间氢键的宽的平面结构的染料分子对于在晶体或薄膜中产生强的分子间pi-pi相互作用对于非线性光学器件是非常重要的。该体系具有较大的光激发极化，有利于制备三阶非线性光学材料。另一方面，我们还合成了多环二硫杂环与TCNQ形成的分子间CT络合物，并对它们的非线性光学响应进行了评价。一些喹类染料通过层间pi-pi相互作用在晶体中产生三维分子堆积，这对产生较大的CH1；我们发现了两类新的喹啉类染料，4，8-二羟基-2，6-二(丁氨基)-1，5-萘醌和1，4-二硫酮-3，6-二苯基吡咯[3，4-c]吡咯，它们是三阶NLO材料的候选者之一。
