摘要：

An unsymmetrical photochromic diarylethene was synthesized and its photochromism and fluorescent properties were investigated in detail. The compound exhibited remarkable photochromism, changing from colorless to violet after irradiation with 297 nm UV light, in which absorption maxima were observed at 535 rim in hexane and at 541 nm in PMMA amorphous films, respectively. The fluorescence intensity of diarylethene 1o decreased upon irradiation with 297 nm UV light, in which fluorescence peaks were observed at 448 rim in hexane and at 426 nm in PMMA amorphous films, respectively. And the modulation efficiency were 12% and 75% in both hexane and PMMA films.
