Formation Reaction, Spectroscopy, and Photoelectrochemistry of the Donor–Acceptor Complex (5,10,15,20-Tetraphenyl-21,23H-porphinato)cobalt(II) with Pyridyl-Substituted Fullero[60]pyrrolidine

Аннотация

Kinetic and thermodynamic parameters of the donor–acceptor self-organization in the system (5,10,15,20-tetraphenyl-21H,23H-porphyrinato)cobalt(II) (CoTPP)–1-methyl-2-(pyridin-4′-yl)-3,4-fullero[60]pyrrolidine (PyC₆₀)–toluene yielding the 1: 2 complex (PyC₆₀)₂CoTPP are presented. The chemical structure of the supramolecular triad was elucidated by UV-vis, IR, and (¹H, ¹³C) NMR spectroscopy. The photoelectrochemical characteristics of the Ti|TiO₂ electrode modified by the triad and its precursors were determined and the redox behavior of the latter was studied by cyclic voltammetry in dichloromethane.
