초록
Poly(p-phenylenevinylene) (PPV)-based copolymer, poly[2-(4'-perfluorodecyl‐1H,1H,2H,2H-dimethylsilylphenyl)-1,4-phenylenevinylene-co-2-(3,7-dimethyloctyloxy)-5‐methoxy‐1,4‐phenylenevinylene] (p-RFSiPh-PPV-co-OC1C10-PPV) have been synthesized by a Gilch polymerization method. Newly synthesized copolymer is highly soluble in common organic solvents. The defect-free uniformly thin films easily formed onto the indium-tin oxide (ITO)-coated glass substrate. The resulting copolymer had high molecular weights with narrow polydispersity and high thermal stability up to 400℃. Double layer organic light-emitting diode (OLED) with an ITO/PEDOT/Polymer/Al configuration was fabricated by using the p-RFSiPh-PPV-co-OC1C10-PPV. The maximum EL emission and brightness of p-RFSiPh-PPV-co-OC1C10-PPV were observed at 588 nm and 1,640 cd/m2 at 9.6 V, respectively.
