Abstract
The photochemical cis—trans isomerization of 1-(9-anthryl)-2-phenylethylenes (9-styrylanthracenes) has been studied by performing steady state and time-resolved fluorescence measurements. It has been found that singlet excited trans isomers are formed from their photoexcited cis precursors and this is explained in terms of an adiabatic photoreaction. Polar solvents and/or polar substituents on the styrylanthracene markedly enhance the adiabatic isomerization.
