摘　　要：通过相转移催化剂PEG-400高产率合成了2个含苯甲酰胺基偶氮苯类化合物,通过核磁共振氢谱,红外光谱元素分析表征了其结构;经365nm的紫外光照射该化合物的DMSO溶液后测其紫外可见吸收光谱,表明化合物具有良好的光致变色性。An efficient and high - yield synthesis of two benzamide azo compounds was accomplished in the presence of PEG - 400 as the phase transfer catalyst. The products were characterized by ^1 H NMR, IR, and elemental analysis. The compounds＇ DMSO solutions were tested after irradiated by 365nm UV light. The results showed that two benzamide azo compounds have good photochromism property.
