键连Y型生色团的无机-有机杂化材料的制备及其非线性光学性能

Preparation and Nonlinear Optical Properties of Organic-Inorganic Hybrid Materials Bearing Y-Type Chromophore

合成了具有两个反应活性中心的Y型有机生色团3-(4’-硝基苯)-5,6-二-(4’-羟基苯)-1,2,4-三嗪(DBPNPT),与硅氧偶连剂异氰酸基-丙基-三乙氧基-硅烷(ICTES)反应生成新型的带有两个活性反应基团的硅氧烷染料DBPNPT-ICTES,并利用溶胶-凝胶技术将其与正硅酸乙酯(TEOS)反应生成双点键连型无机-有机杂化薄膜材料。经溶剂变色法计算生色团DBPNPTβCTμg值为37.9*10-30esu·D,并且生色团和硅氧烷染料具有良好的可见光波段透明性,较好的解决了"非线性-透明性矛盾"。

A novel Y-type chromophore named 5,6-bis （4- hydroxyphenyl）-3-（4-nitrophenyl）- 1,2,4-triazine （DBPNPT） and its corresponding silicon alkoxysilane dye DBPNPT-ICTES were synthesized. The organic-inorganic films containing the newly synthesized chromophore DBPNPT were prepared by co-hydrolysis/condensation process with TEOS. The βCTμg value of chromophore was determined to be 37.9＊10^-38esuoD by solvatochromic method. Both of the chromophore and hybrid materials have a high melting point and a good transparency in visible wavelength.
