Abstract :
Evidences of the π-stacking of rhodamine B onto poly(sodium 4-styrenesulfonate) are given by 1H NMR spectroscopy. As a consequence of these π–π interactions, changes on the diafiltration and UV–vis absorbance and fluorescence patterns are shown comparing water-soluble polymers containing aromatic rings as poly(sodium 4-styrenesulfonate) and poly(N-methacryloyl-5-aminosalicylic acid) with other polyanions that do not contain aromatic rings as poly(sodium vinylsulfonate) and poly(acrylic acid).
