Transfer of excitation energy in rigid solutions containing charge-transfer complexes. Part 2.—Photoconductivity

Abstract

Photoconductivity of polystyrene doped with anthracene (donor), chloranil or trinitrobenzene (acceptor) was investigated by studying the spectral sensitivity, the dependence on donor and acceptor concentration, and the dependence on excitation intensity of the photocurrent.

It was found that the most likely process of carrier generation is formation in an anthracene-acceptor complex. The results are in good agreement with predictions based on observations of fluorescence quenching in these systems.
