In this paper, the fluorescence spectra of model compounds of light-emitting alternating copolymers, M (TPA-PPV) and M (TPA-PAV) (Scheme 1) were studied and the effect of KNO₃ on the interaction between model compounds and ionic micelle-water interface was also investigated. It is found that (I) The fluorescence changes of M (TPA-PPV) are related to the state of CTAB and SDS solution. (Ⅱ) Aggregated state can be formed in M (TPA-PAV) solution at low concentration of CTAB. (Ⅲ) Higher concentration of KNO₃ may affect the interaction between model compounds and ionic micelle-water interface.
