Fluorescence investigation of model compounds for light-emitting alternating copolymers in heterogeneous environments.
In this paper, the fluorescence spectra of the model compounds M(TPA-PPV) and M(TPA-PAV) of novel light-emitting alternating copolymers, were studied and the effect of KNO3 on the interaction between the model compounds and the ionic micelle-water interface was also investigated. The following is found: (i) the fluorescence changes of M(TPA-PPV) are related to the state of cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) solution: (ii) an aggregated state can be formed in M(TPA-PAV) solution at low concentration of CTAB; (iii) higher concentrations of KNO3 may affect the interaction between the model compounds and the ionic micelle-water interface.

Photophysical processes of a copolymer containing 1,1'-binaphthyl-2,2'-diamino and carbazolyl units.
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.
