Paper Abstract

The reversible molecule switching of an assymmetrical photochromic diarylethene 1-(2-methyl-5-phenyl-3-thienyl-2-[2-methy1-5-(4-ethoxylpheny1) -3-thieny1]perfluorocyelopentene (MPTMEPTF6) has been prepared for the examination of photo-switching, fluorescence switching. The photochromism properties of MPTMEPTF6 diarylethene show good photochromism in hexane and in PMMA amorphous film. Steady state fluorescence studies indicated that MPTMEPTF6 diarylethene is higher fluorescent in the open-ring isomer, but there almost no fluorescence in the closed-ring isomer in PMMA amorphous film. The diarylethene MPTMEPTF6 has promising application for photo-switching, fluorescence-switching which can use for data storage.
