Notes:
The interaction between 2-p-toluidinylnaphthalene-6-sulfonic acid (TNS), a hydrophobic fluorescent probe, and poly(2-vinylpyridinium) polyions (PVP) has been investigated by fluorescence spectroscopy. Both the effect of the charge and the concentration of PVP on the fluorescence behavior of TNS indicate that interaction between TNS and hydrophobic sites present in the PVP chain is responsible for the observed phenomena. It is shown that PVP which exists with predominant hydrophobic regions leads to TNS fluorescence, but some residual charge must be present to facilitate the penetration of the dye into the hydrophobic regions. Various situations existing in some polyelectrolyte systems are discussed.
