Abstract
The photochemistry of trans - and cis -1-(1′-naphthyl)-2-(3-hydroxyphenyl)ethene in cyclohexane and acetonitrile was examined. In cyclohexane fluorescence is the main deactivation channel for the^1 trans * isomer while photocyclization is the main reaction of the^1 cis * isomer. The weighty formation of hydroxychrysene following one photon absorption by the trans isomer furnished evidence of an adiabatic^1 trans *→^1 cis * isomerization. The photoreactivity data in acetonitrile indicated the influence of solvent polarity on the shape of the excited state surface.
