Chemical synthesis of two C-60 fullerene derivatives: with porphyrin (C-60-H2P) and of the iodide salt of Zn porphyrin (C-60-ZnP)I-+(-) is described. Both compounds are soluble in several organic solvents, with a larger solubility observed for C-60-H2P. Thin films obtained by solution drawing or by spinning techniques from C-60-H2P solution in organic solvents or dissolved in a polymer matrix show a peculiar granular structure with regular submicron size particles. Their size of is a little smaller in polymer matrix. The solution UV-Vis absorption spectra exhibit typical bands which can be attributed to porphyrin and to the fullerene. A solvatochromic effect is observed in C-60-H2P which shows a nonzero first hyperpolarizability beta, most likely due to the charge transfer between fullerene and porphyrin.
