Abstract

The photocyclization quantum yield of 2,2′-dimethyl-3,3′-(perfluorocyclopentene-1,2-diyl)bis(benzo[b]thiophene-6-sulfonate) is found to increase in aqueous solution after the addition of β- and γ-cyclodextrin, in which a photoreactive antiparallel conformation of diarylethene is favourably included.
