新型偶氮苯并冠醚衍生物在溶液和LB膜中的光致变色研究

Study on the Photoinduced-color Changing about Novel Azobenz ocrown Ether Derivatives 16ABC-OH and 16ABC-NH_2 in Water Solution and Langmu ir-Blodgett Film

本文合成了两种新型偶氮苯并冠醚衍生物 16 ABC- OH和 16 ABC- NH2 ,并对其在溶液中和L angmuir- Blodgett膜中的光致变色现象进行了研究。结果表明 :在溶液中 16 ABC- OH发生了反式 -顺式异构化反应 ,且异构化反应为一级反应 ,而 16 ABC- NH2 的顺反异构化反应较复杂 ,为非一级反应。在 L B膜中 ,16 ABC- OH无光组合记录且有一定程度的光致顺反异构反应 ,而 16 ABC- NH2 自组合形成 H-聚集体且光致变异构反应被禁阻。

Two kinds of azobenzocrown ether derivation 16 AB C-OH and 16ABC-NH 2 have been synthesized,and their photoinduced color changi ng phenomena has been investigated in water solution,the reaction of 16ABC-OH i s the photochmical Cis-trans-isomerization,and it is a first-order reaction,b ut the reaction of 16ABC-NH 2 photochemical Cis-trans-isomeriation is very c omplex;and it is not a first-order reaction.In Langmuir-Blodgett film of16ABC -OH,there is not molecular self-assembly phenomenon,the part of Cis-16ABC- OH become to iso-16ABC-NH 2,but in the film,16ABC-NH 2 form H-Polymer by s elf-assembly,and the photochromic Cis-trans-isomerization is forbided.
