The relaxation of electronically excited styrenes: a ‘twisted’ excited state

Abstract

Gas-phase studies of a series of styrene derivatives have provided evidence for relaxation from initially excited 1La states to ‘twisted’ singlet states which have anomalously long lifetimes. By examining derivatives with different constraints for rotation about the excited π-bond it has been demonstrated that it is a change in excited state geometry involving some rotation which controls the efficiency of population of the long-lived singlet states. Comments on a recent analysis of the solution phase photophysics of cyclic styrene derivatives are made.
