This work reports on synthesis and characterizations of cobalt(II) complex 1Co with octopus-like phthalocyanine ligand bearing eight peripheral O-benzyl-diethyleneglycol substituents. Concentration-dependent investigation of UV-Vis spectra of 1Co in chloroform evidenced of its aggregation at high concentrations (0.3 mМ) with the formation of dimers with dimerization constant (4.8±0.2)∙10³ M^-1.Supramolecular assembling of 1Co with fullerene C₇₀ was studied by UV-Vis titration and by ESR spectroscopy. Both methods suggest the absence of notable interactions between electronic systems of 1Co and C₇₀ in ground state, the formation of the assembly 1Co•C₇₀ occurs via noncovalent interactions.
