摘要: 研究了萘并吡喃的光致变色原理及结构特征,通过萘并吡喃类化合物光致结构互变时的关键化学结构点,分别考察了在萘环上引入含氮推电子基团,在3位苯环上引入含氮推电子基团,在吡喃部位稠合引入金属茂结构,通过碳原子或杂原子桥连的3-位苯环的稠合,对拓展π结构后的萘并吡喃化合物光致变色性能的影响也做了探讨.此外,还考察了引入取代基的共面控制及对共轭体系的影响.

关键词: 萘并吡喃, π结构, 共面, 光致变色

Abstract: The naphthopyrans compounds were structurally modified to extend π conjugation system by introducing N containing donating groups, metallocenyl groups, heterofused groups and thioxanthene groups. The photochromic properties and the conplanarity of substitutes to the main plane were discussed as well.

Key words: naphthopyran, π conjugation, conplanarity, photochromism
