Syntheses and Properties of a Symmetrical Photochromic Diarylethene
Abstract:
A new photochromic diarylethene compound 1,2-(2-ethyl-3-benzofuryl) perfluorocyclopentene was synthesized. And its properties including photochromism, fluorescence both in hexane and solid films were studied. And its absorption maxima were observed at 489 nm in hexane and at 499 nm in PMMA films, respectively, upon irradiation with 313 nm UV light. The fluorescence intensity of diarylethene decreased upon irradiation with 313 nm UV light. And the fluorescence modulation efficiency was better in PMMA films than that in hexane.
