Two novel azobenzene compounds containing ehiral carbon, 4-(formic acid ethyl lactate ester)-4'-N, N-bi-methyl azobenzene and 4-(formic acid ethyl lactate ester)- 4'- N, N-bi-methyl bi-azobenzene, had been synthesized by reactions of sulfonyl chlorination and esterfication. The azobenzene compounds containing chiral carbon were characterized and detected by paper chromatography method and Infrared (IR) spectrum. The Ultraviolet-visible light (UV-Vis) spectrum results showed that the two compunds have good photochromism properties and the chiral carbon had significant effect on UV-Vis spectrum. Research shows that single-azobenzene structure of the compound has larger transformation in the absorption spectrum than bi-azobenzene structure of the compound.%采用重氮化偶合反应合成得到偶氮苯染料母体,再经酰氯化、酯化反应合成出两种新型的含手性碳的偶氮苯化合物4-甲酸乳酸乙酯酯基-4'-N,N-二甲基偶氮苯和4-甲酸乳酸乙酯酯基-4'-N,N-二甲基双偶氮苯,并用纸色谱、傅里叶红外(IR)光谱进行了监测和表征.经紫外一可见光(UV-Vis)光谱测试表明两种化合物显示出良好的光致变色性能,与母体化合物的对比可以看出,接入手性碳后光致变色光谱表现出明显的变化,且单偶氮结构的化合物要比双偶氮结构的化合物光致变色光谱明显.
