Abstract

Single crystals of the closed-ring isomer of the diarylethene derivative 1,2-bis(2-methyl-6-styryl-1-benzothiophen-3-yl)perfluorocyclopentene underwent a ring-opening reaction with high conversion while keeping their crystalline shape and transparency. Polar plots of the absorption anisotropy revealed that the closed-ring isomer in the crystal maintained an ordered alignment even at high conversion, and the transparency of the single crystal remained intact during photoreaction. X-ray crystal structural analysis showed that the length of the b axis of the unit cell increases as the photoreaction proceeds. The photostimulated crystal-lattice change is attributed to the rotational movement of the thiophene rings of the molecule during the photochemical ring-opening reaction.
