A new class of blue light-emitting PPV derivative, poly(9,9-dialkylfluorene-2,7-vinylene) (PAFV), was synthesized and reported by S.H. Jin et al. High molecular weight PAFV has been obtained through Gilch polymerization route. PAFV showed efficient blue light emission. In this study, we synthesized a class of statistical copolymers including 9,9-dialkylfluorene-2,7-vinylene in order to improve EL efficiency and also to control the emission wavelength. For the purpose, series of poly[(9,9-dioctylfluorene-2,7-vinylene)-co-(1,4-phenylenevinylene)] [Poly(OFV-co-PV)] and poly[(9,9-dioctylfluorene-2,7-vinylene)-co-(2-methoxy-1,4-phenylene vinylene)] [Poly(OFV-co-MPV)] have been synthesized and their light-emitting properties were investigated. |
