Excited-state reactivity of 2,4,6-triphenylpyrylium ion (TPP+) with cinnamates has been studied by fluorescence quenching and laser flash photolysis experiments.Electron-transfer reactions between cinnamates and excited states of TPP+ are reported.The pyryl radical (TPP*) has been observed as an intermediate.In the singlet manifold, dimerization product(s) are reported and in the triplet manifold the trans-cis isomerization product is reported.Selectivity of oxygen in the product formation is observed.This is one of the few systems in which both isomerization and dimerization mechanisms are operating together through a radical cation intermediate.For the first time the dimerization of cinnamate derivatives via a radical cation is reported.
