摘　　要：用125 W的高压汞灯照射,用紫外-可见分光光度计测试合成的2个偶氮化合物的光致变色性。结果表明,热对2个偶氮化合物的光反应具有干扰作用,当消除热干扰,2个偶氮化合物具有较好的光致变色性,在热的作用下具有热致变色性;而在光和热同时作用时,2个化合物均未表现出变色性质。因此,在测试偶氮化合物光致变色性质时要避免热的干扰作用。Two azo compounds were irradiated by high-pressure mercury lamp （125 W） to test photochromism. By investigated their ultraviolet absorption, the results indicated that thermal energy interfere with the photochromic test. It was showed that two compounds have good photochromic when get rid of the influence of thermal energy and have thermochromism behavior, but both of them didn＇t have characteristic when the UV light and thermal worked together. So it was necessary to avoid the interference of thermal energy when test azo compound＇s photochromism.
