The photo-valence-isomerization of 1-(p-dimethylaminophenyl)-4-aryl-cycloheptatrienes has been studied.The photoreactive state is assumed by a long wave emission state.The dependence of reaction quantum yields on solvents and substituents points out that the reactive state is not very polar contrary to the assumption in the literature.Reactivity indices from front orbitals cannot describe the ring closure.The parameters for thermically induced cycloreversion are discussed.
