N2 - The copolymer of polyfluorene/poly(p-Phenylene vinylenes) (PFO/PPV) was synthesized through Heck reaction. The structure of the obtained copolymer was characterized by FT-IR, 1H NMR, TGA, etc. The molecular weight and poly dispersity of the copolymer were 4400 and 1.2, respectively. The copolymer had good thermal stability, it had only one weightlessness from RT to 700°C and the weightlessness was about 50% at 350~450°C. E HOMO/E LUMO and E g was -6.09/-3.20 and 2.89 eV respectively. The optical properties, revealed by UV-Vis and PL, showed that copolymer had excellent luminescence, with a maximum peak of fluorescence emission at 490 nm. The copolymer was also tested as an emitting layer for flexible polymer light-emitting diode (PLED) device, where nano ZnO as a functional layer, showing a turn-on voltage of about 4.2 V and emitting blue electroluminescence.
