Abstract

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

H NMR

TGA

etc.

The molecular weight and poly dispersity of the copolymer were 4 400 and 1.2

respectively. The copolymer had good thermal stability

it had only one weightlessness from RT to 700 ℃ and the weightlessness was about 50% at 350~450 ℃.

LUMO

and

was-6.09/[KG-*4]-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.
