Article abstract of DOI:10.1246/cl.2003.858

Highly efficient photocycloreversion reaction was observed for diarylethene derivatives with cyano groups at the reactive carbons of the thiophene rings. The cycloreversion quantum yield of 1,2-bis(2-cyano-5-phenyl-3- thienyl)perfluorocyclopentene was fou
