Fluorescence spectra of liquid solutions of PVCA are dominated by two kinds of excimer emission which are characteristic for the mode of preparation of the polymer. Luminescence spectra of solid solutions are more monomer‐like, indicating shallow exciton traps. Substantial hypochromic effects are reported for the two lowest energy singlet transitions of PVCA. No significant difference could be observed for PVCA samples of cationic and radicalic origin.
