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-FulleroPyrrolidine
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 (CoIITBPP) with 1-methyl-2-(pyridin-4′-yl)-3,4- fulleropyrrolidine (PyF) in toluene at 298 K, ending by the formation of donor-acceptor triad (PyF)2CoIITBPP, 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.
