Paper Title:
Optoelectronic Properties and Holographic Optical Recording of a Unsymmetrical Diarylethene Having a Pyrrole Unit
  Abstract

A unsymmetrical photochromic diarylethene, 1-[2-methyl-5-(3,4-difluorophenyl) -3-thienyl]-2- (2-cyano-1,5-dimethyl-4-pyrryl) perfluorocyclopentene (1o), was synthesized, and its optoelectronic properties were also investigated. The results showed that this compound exhibited reversible photochromism changing from colorless to blue after irradiation with UV light both in solution and in PMMA amorphous film. The open-ring isomer of the diarylethene 1 exhibited relatively strong fluorescence both in hexane solution. The fluorescence intensity decreased along with the photochromism upon irradiation with 297 nm light and its closed-ring isomer showed almost no fluorescence. Using diarylethene 1 as recording medium, polarization holographic optical recording was carried out successfully.
