The synthesis of (Octakis(3,5-di-tert-butylphenoxy)phthalocyaninato) cobalt(II) (CoPc(3,5-di-tBuPhO)8)
was reported. The new phthalocyanine complex was characterized by UVevis, IR, 1H NMR and mass
spectra and elemental analysis. The supramolecule formation reactions of CoPc(3,5-di-tBuPhO)8 with
pyridine (Py) and 20-(4-pyridyl)-50-(2-pyridyl)-10-(3-pyridylmethyl)pyrrolidino[30,40:1,2][60]fullerene
(Py3F) were studied in toluene by methods of chemical kinetics and thermodynamics, UV, visible, IR and
1H NMR spectroscopy. The addition of pyridine results in single-stage equilibrium between the donoracceptor
complex 1:1 and the initial cobalt phthalocyanine. The reaction with the substituted
fullerene goes to the formation of phthalocyanine - fullerene 1:1 supramolecule in the kinetic mode. The
product of supramolecular complexation were identified by spectral methods.
