Abstract:
The photophysical processes of copolymer formed by copolymerization of 2,2'-dimethacrylamido-1,1'-binaphthyl (DMBN) with vinylcarbazole (VCZ) have been carefully studied. The results show that when the solution of copolymer (DMBN-VCZ) in THF located in low concentration range (< 10(-3) mg/ml), the fluorescence emission is in good agreement with that of DMBN monomer and the excimer is formed with gradual increase in concentration of copolymer (DMBN-VCZ). The fluorescence of copolymer (DMBN-VCZ) can be quenched both by electron donors and acceptors where the quenching effects follow the Stern-Volmer equation. The dimolecular exciplex between copolymer (DMBN-VCZ) and N,N-dimethylaniline (DMA) are formed and the triple exciplexes are also observed in the same system.
