新型对称双偶氮苯化合物的合成及光学性能

摘要

以联苯二胺为原料,通过重氮化、偶联和Williamson醚合成反应,设计合成了一系列新型的对称性不同端基的双偶氮类化合物,考察了溶剂、不同取代基对偶氮化合物紫外吸收影响.以4,4’-二(4-辛氧基-苯偶氮基)-联苯( Azo3)为例,在365 nm紫外光照射下发生反-顺光异构化,光照10 min后达到光稳定态,具有良好的光致变色性.%A series of novel symmetrical disazobiphenyl compounds with different substituent were synthesized through diazotization reaction T coupling reaction and Williamson reaction with benzidine as raw material. The influences of solvent and substituent on maximum absorption wavelength were discussed. The photochromism of disazobiphenyl compound (Azo3 ) has been studied by UV-Vis spectrum under irradiation of 365 nm light and the photostationary state was obtained after irradiation for 10 min.
