## Abstract Bis(3βthienyl)perfluorocyclopentenes containing partially fluorinated thiophene rings were synthesized and their behaviors examined. Dithienylethenes containing chlorinated thiophene rings were also prepared as reference compounds. The absorption maxima of the closedβring isomers, their
Only one photo-induced cyclization reaction occurs when two 1,2-dithienylethene photochromes are covalently joined. Attempts made to ring-close the second photochrome by prolonged irradiation quantitatively produced a rearranged product that could not be photobleached.
