Paper Title:
Synthesis, Properties and Application in Optical Memory of a Photochromic Diarylethene Based on Benzene Ring
  Abstract

A new photochromic diarylethene compound, 1-(2-methyl-5-(2,4-difluorophenyl)-3-thienyl)-2-(2-cyanophenyl)perfluorocyclopentene (1a), was synthesized and its photochromism and photo-induced anisotropy was investigated. The results showed that this compound exhibited reversible photochromism, changing from colorless to purple after irradiation with UV light both in solution and in PMMA amorphous film. In hexane, the open-ring isomer of the diarylethene 1a exhibited relatively strong fluorescence at 459 nm when excited at 316 nm. The fluorescence intensity decreased along with the photochromism upon irradiation with 297 nm light and its closed-ring isomer showed weak fluorescence.
