Spectroscopic and Electrical Properties of Polymeric Donor—Acceptor Complexes

The spectroscopic and electrical properties of poly (p-dimethylaminostyrene) complexes with a variety of electron acceptors have been measured. Weak electron acceptors yield charge-transfer complexes, whereas strong electron acceptors are partially converted into radical anions. As may be concluded from measurements of the Seebeck coefficient, charge transport is caused by electrons. The electrical conductivity of the complexes is critically dependent on acceptor concentration and is attributed to hopping processes between radical anions and neutral acceptor molecules.
