Study on Photochromic Perfluorocyclopetene Containing Six-Numbered Unit as Optical Recording Materials

Abstract

A reversible molecule switching of symmetrical photochromic diarylethene 1,2-bis methyl phenyl perfluorocyclopentene has been synthesized and its photochromic and simulated molecule structure were also investigated. The compound exhibited photochromism both in solution and PMMA film but no photochromism in solid state. In hexane, the open-ring isomer of the diarylethene1oshowing an absorption peak at 308 nm. Upon irradiation with 313 nm light, a new absorption band in the visible region centered at 595 nm emerged to form closed isomer1c. This compound can be used as optical recording materials.
