N2 - A series of π-conjugated polymers alternatively involving m-phenylenevinylene or p-phenylenevinylene and a triphenylamine moiety in the main chain, poly(triphenylamine-alt-phenylenevinylene)s, were synthesized and their optical and electroluminescent properties were studied. Single-layer light-emitting diodes based on each polymer showed a strong blue-yellow-green emission ascribed to their band gaps, and exhibited small turn on voltages and large current densities. The device containing poly(4-methyltriphenylamine-alt-p-phenylenevinylene) (MPA-pPV) displayed a high brightness (640 cd/m2 at 10 V). These results suggest that the polymers have a good charge transporting ability and an electroluminescent property.
