A series of block copolymers containing carbazole groups were synthesized via reversible addition fragmentation chain transfer (RAFT) polymerization of styrene monomer. Then the block copolymer containing carbazole groups and europium complex was synthesized by coordination. The block copolymers were characterized by elemental analyses, FT-IR, 1HNMR, GPC, Uv-vis absorption, fluorescence spectroscopy and cyclic voltammetry. The GPC result shows that the block copolymers have narrow polydispersity and controlled molecular weights (MWs). The fluorescence spectroscopy of the block copolymer containing carbazole groups and europium complex shows red emission assigned to f-f transitions of europium ions in solid state. In addition, the presence of europium complex in the block copolymer was further evidenced by fluorescence characteristic of europium ions. The CV data reveals that in the block copolymer containing carbazole groups and the europium complex a balance can be achieved between electron currents and the electron-hole currents. Thus, the copolymer is a potentially useful candidate for fabricating memory or light emitting devices.
