The interaction of sulfonated tetraphenylporphins H{sub 2}TPPS{sub 4}(HCl){sub 2} and in CuTPPS{sub 4} with poly-N-vinylpyrrolidone (PVP) is studied using small-angle neutron scattering, dynamic light scattering, visible spectrophotometry, and viscometry. It is shown that porphyrin molecules form complexes with PVP, thus charging the polymeric chain.
