Formation Reaction and Chemical Structure of a Novel Supramolecular Triad Based on Cobalt(II) 5,10,15,20-(Tetra-4-Tert-Butylphenyl)-21Н,23Н-Porphyrin and 1-Methyl-2-(Pyridin-4′-Yl)- 3,4-Fullero[60]Pyrrolidine

Abstract

Results of chemical kinetic/thermodynamic and spectroscopic studies of the reaction of cobalt(II) 5,10,15,20-(tetra-4-tert-butylphenyl)-21Н,23Н-porphyrin (Co^IITBPP) with 1-methyl-2-(pyridin-4′-yl)-3,4- fullero[60]pyrrolidine (PyF) in toluene at 298 K, ending by the formation of donor-acceptor triad (PyF)₂Co^IITBPP, are presented. Kinetic and thermodynamic parameters of the two-way formation reaction of the triad are obtained. The chemical structure of the obtained porphyrin-fullerene triad is identified by UV, visible, fluorescent, IR, and ¹H NMR spectroscopic techniques. The results are relevant for the problems of searching for supramolecular systems capable of photoinduced charge separation.
