A molecular switch based on a blue photochromic diarylethene

摘要

A new blue photochromic diarylethene compound, 1-[5-(3,5-difluorinphenyl)-2-methyl-3-thienyl]-2-[5-(3-cyanophenyl)-2-methyl-3-thienyl]perfluorocl opentene (1a), was synthesized and its photochemical properties were investigated in detail. The results demonstrated that the compound has good photochromism in solution and in PMMA amorphous film, and good fluorescence and optical storage properties.
