We have reported the luminescent and photochemical behaviors of poly(4-vinylpyridine) (P4VPy) and derivatives in solid. To analyse the complicated emission bands of these poly(vinylpyridines) (PVPys), we induced the Emission Contour Maps (ECMs) in our previous report. With ECMs, the emission bands originated from free-PVPys, hydrogen-bonded PVPys, protonated PVPys, and quaternized PVPys appeared to have some characteristics. Though PVPys are said that they show similar absorption spectra in free or protonated states, their emission bands and emission yields are significantly influenced with protonation. In our previous study, the change in proton / hydrogen (H+/H) concentration seemed to increase difficulties on the analysis of these emission bands. To avoid the change in H+/H concentration, we used a polymeric H+/H donor, poly(acrylic acid)(PAA). The ECMs of resultant polymer complexes between PVPys and PAA were determined. Some features of the emission bands in their ECMs were discussed.
