Equilibria and Rates of Reactions between Organic N-Bases and Substituted Manganese Phthalocyanine

The direction, stoichiometry, and rate of reactions between pyridine/pyrimidine/pyrazine/4-picoline/2-(pyridin-4-yl)-5-(pyridin-2-yl)-1-(pyridin-2-yl)methylpyrrolidinyl[3,4:1,2][60]fullerene and (octakis(3,5-di-tert-butylphenoxy)phthalocyaninato) manganese(III) acetate in toluene are studied via chemical thermodynamics/kinetics and spectroscopy. All the reactions proceed through the one-step coordination of base molecules on the manganese atom in the phthalocyanine complex, which ends with the formation of a molecular (neutral or cationic) 1:1 complex. Numerical values are obtained for the equilibria/rate constants of reactions and the key spectral characteristics of the intermediate and the products. The correlation between reaction parameters and chemical structure of reagents is examined, and recommendations for applying the results in the chemistry of materials based on phthalocyanines are given.
