The fluorescence spectra of poly(2-vinylpyridine)s (P2VPs) were measured in solution at room temperature in the presence of trifluoroacetic acid(TFA) as a function of average degree of polymerization (D-P). All protonated P2VPs exhibited a dimer-like excimer and normal excimer fluorescence around 32
