Diarylperfluorocyclopentenes having 2-methoxy-5-phenylthiophene as the aryl groups were synthesized. Introduction of two methoxy substituents instead of methyl groups at the reactive carbons of 1,2-bis(5-phenyl-3-thienyl)perfluorocyclopentene decreased the photocyclorever-sion quantum yield by a factor of 103, while the cyclization quantum yield was similar.
