Title
Photo- and electroluminescence in a series of PPV type terpolymers containing fluorene, thiophene and phenylene units
Abstract

The emissive properties of terpolymers with fluorene, thiophene and phenylene groups, forming alternating PPV type structures, are discussed in terms of their composition, photo- and electroluminescence properties. The fluorene groups were inserted in each phenylene–vinylene and thiophene–vinylene units, and their concentration did not vary, representing 50% of the molar composition. The ratio of thiophene–vinylene/phenylene–vinylene varied in the range 25, 50 and 75%. Photo- and electroluminescence properties were strongly dependent on the thiophene–vinylene content and were compared with the fluorene–vinylene–thiophene and fluorene–vinylene–phenylene parent copolymers.
