Abstract

The abilities of a variety of inorganic and organic compounds to act as electron transfer quenchable light absorbers in thin polymeric films have been examined. The compounds, each of which contains a primary amine, were chemically bound in precast chlorosulfonated polystyrene films by sulfonamide bond formation. Visible photolysis of the films in the presence of an oxidative quencher and a reductive scavenger leads to a sustained photocurrent response from 14 of the 18 compounds studied. Differences in the photocurrent output as the chromophore is changed can be explained qualitatively based on a kinetic model whose key steps are optical excitation of the absorber followed by excited state electron transfer.
