Water-soluble poly(N-vinylpyrrolidone)fullerene C-60-tetraphenylporphyrin complex

Water-soluble complexes of poly(N-vinylpyrrolidone) with meso-tetraphenylpo rphyrin and poly(N-vinylpyrrolidone) with meso-tetraphenylporphyrin and ful lerene C-60 were prepared. The comparative spectral analysis of these syste ms with the poly(N-vinylpyrrolidone)-fullerene C-60 system showed that, in the porphyrin-containing systems, the interaction between the system compon ents and the polymer can be interpreted in terms of molecular adsorption. O n the basis of the analytical data, it is suggested that an increase in the relative C-60 concentration in the ternary complex in water is associated with a rather low local polarizability of the polymer molecules which form a shell around this center, compared to the polymer-fullerene binary system , where a significantly greater number of polymer macromolecules are associ ated around C-60.
