Experimental Measurement of Fatigue Resistance of a Photochromic Diarylethene

In particular, diarylethenes have become the promising candidates of photo- chromic compounds because of the excellent thermal stability of both isomers and resistance to high fatigue.

Based on summarizing diversified performance of the diarylethene compounds,this review has a closer look of properties that can be photoswitched by using diarylethenes as a photoswitching of fluorescence,fluorescence resonance energy transfer,photoswitching of electrical conductivity, magnetism,liquid crystal and muti-addressable photochromic switches.

1,2-diarylethenes are promising molecules to be used as photochromic memory materials and molecular switches due to their excellent thermal stability and fatigue resistance.

Finally, a novel photochromic dithienylethene compound, 1,2-bis[2-methyl-5-(3,4-difluoro-phenyl)-3-thienyl]perfluorocyclopentene (DT-1), was synthesized by the reaction of 4 with perfluoro-cyclopentene at-.

Two photochromic dithienylethene compounds,1,2-bis[2-methyl-5(p-N,N-dimethylamino- phenyl)-3-thienyl]perfluorocyclopentene(Ⅰa) and 1,2-bis(2-methyl-5-naphthalene-3-thienyl)perfluorocyclopentene(Ⅱa) were synthesized,and their optoelectronic properties and electrochemical properties were systematically investigated.
