Abstract
A new photochromic diarylethene, 1-(2-cyano-1,5-dimethyl-4-pyrryl)-2-[2-methyl-5-(10-phen-anthrenyl)-3-thienyperfluorocyclopentene was synthesized and its photochromic and fluorescent properties were also systematically investigated. The results showed that this compound exhibited reversible photochromic, changing from colorless to blue after irradiation with UV light in both solution and PMMA amorphous film. The fluorescence intensity declined along with the photochromic when irradiation with UV light. However the fluorescence switch in PMMA amorphous film showed more remarkable than in solution.
