Epub 2011 Dec 19.The present article reports for the first time on supramolecular interaction between fullerenes (C60 and C70) and a designed monoporphyrin in solution, e.g., 5,10,15,20-tetrakis(4-methoxyphenyl)-21H,23H-porphine (1), in absence and presence of silver nanoparticles (AgNp) having varying diameter of range between 3 and 7 nm. Ground state electronic interaction between fullerenes and 1 has been evidenced from the observation of decrease in the intensity of the Soret absorption band of 1 after complexation with C60 and C70 in toluene.
