چکیده
An asymmetrical photochromic diarylethene 1-(2cyano-1,5-dimethyl-4-pyrryl)-2-{(2-methyl-4hydroxymethylphe -nyl)-3-thienyl}perfluorocyclopentene (1o) was synthesized and its photochromic properties as well as reaction kinetics were investigated in detail. Upon irradiation with 297 nm UV light, diarylethene 1o exhibited photochromism in solution. Moreover, 1o also exhibited obviously fluorescence switches along with the photochromism. Keywords-diarylethene; photochromic; fluorescence; pyrrole
