Synthesis and characterization of a copolymer containing 1,1'-binaphthyl-2,2'-diamino and carbazolyl units

摘要

A novel copolymer has been synthesized by copolymerization of 2,2'-dimethacrylamido-1,1-binaphthyl (DMBN) with vinylcarbazole (VCZ) and its fluorescence characterization has been studied. The results show that the copolymer (DMBN-VCZ) is soluble in some common organic solvents and the fluorescence of the copolymer (DMBN-VCZ) can be quenched by both electron donors and electron acceptors where the quenching effects follow the Stern-Volmer equation. The dimolecular exciplexes between copolymer (DMBN-VCZ) and strong electron donor or electron acceptor are formed. Moreover, the interaction between copolymer (DMBN-VCZ) and C{sub}60 is also studied by fluorescent quenching.
