Copolymers containing 9,9-dioctylfluorene and terephthalate units [as dimethyl ester (F1) or free acid (F2)] were synthesized by Suzuki coupling reaction and characterized by GPC and 1H NMR, FT-IR, and UV-VIS spectroscopies. These copolymers proved to be good luminescent materials showing emission in the blue region of the visible spectrum both in solution and thin layers (l_em= 450 nm). Polymers (F1, F2) were used as donor ligands in europium complexes and for electroluminescence measurements.
