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.
