Five new diarylethenes based on a hybrid structure of bis (5-thiazolyl) ethene and bis (3- thienyl) ethene were synthesized, and the structures of the four compounds were determined by single-crystal X-ray diffraction analysis. The properties of these diarylethenes, such as photochromism, fluorescence, and electrochemical properties were investigated in detail. All of these compounds showed good photochromism and fluorescence both in ...
