Study on Composite Synthesis and Properties of a Novel Diarylethene Material Bearing Nitrile Group


Article Preview

A new unsymmetrical photochromic diarylethene, 1-(2-methyl-5-methylenehydroxyl-3-thienyl)-2-(2-cyanophenyl)perfluorocyclopentene(1a) was synthesized, its photochromic properties were examined, the result indicated that the diarylethene 1a changed the color from colorless to red upon irradiation with 297 nm UV light, in which absorption maxima were observed at 510 and 523 nm in hexane and PMMA film, respectively. In hexane solution, the open-ring isomer of the diarylethene 1 exhibited relatively fluorescence at 441 nm when excited at 294 nm.
