Abstract

The photoluminescence (PL) and electroluminescence (EL) properties of two series of novel silole-containing polyfuorenes were comparatively investigated. The band gaps of the copolymers could be tuned by structural designing of siloles and control of molar ratios of the siloles in the copolymers. The copolymers showed strong intra- and inter-molecular energy transfer in the solid state, from which the blue emission from polyfluorene could be suppressed and green and red EL devices based on the two series of copolymers could be achieved. Photovoltaic cell and field effect transistor properties of some copolymers were also evaluated.
