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 synthe- sized through diazotization reaction, coupling reaction and williamson reaction with benzidine as raw mate- rial. 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 irradia- tion of 365 nm light and the photostationarv state was obtained after irradiation for 10 min.
