Donor/acceptor-substituted phenylenevinylenes

The incorporation of donor/acceptor moieties into poly(p-phenylenevinylene) has been accomplished by a simple cation-anion coupling reaction. The reaction was used to create a series of oligomers, which were then investigated by dielectric spectroscopy in order to study strong dipole moments along the conjugated chain. The information obtained by this method should elucidate cooperative dipole-dipole interactions and help to improve the poling stability of polymers in nonlinear optical devices.
