A Molecular Switch Based on a Blue Photochromic Diarylethene
A new blue photochromic diarylethene compound, 1-[5-(3,5-difluorinphenyl)-2-methyl-3-thienyl]-2-[5-(3-cyanophenyl)-2-methyl-3-thienyl]perfluoroclopentene (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.
