Photochromism and Fluorescent Switch Material of a Novel Diarylethene Bearing Phenanthrene Unit
Abstract:
A novel photochromic diarylethene, 1-(2,5-dimethyl-thienyl)-2-[2-methyl-5-(10-phen-anthrenyl)-3-thienyPerfluorocyclopentene was designed and synthesized, and its photochromic and fluorescent properties were also investigated in detail. The compound exhibited remarkable photochromism, changing from colorless to violet after irradiation with UV light both in solution and in PMMA film. The fluorescence intensity declined remarkably, when irradiation with UV light. Using this diarylethene 1o as optical storage was performed successfully.
