- Abstract
ect of substituents on the spectral, coordination, and fluorescent properties of acetonitrile solutions of asymmetrically substituted tetraphenylporphyrins, namely 5-(4-aminophenyl)-10,15,20-triphenylporphine, 5-[4-(glycylamino)phenyl]-10,15,20-triphenylporphin, and 5-[4-(N-tert-butoxycarbonylglycylamino)phenyl]-10,15,20-triphenylporphin, was studied. The kinetic parameters of formation of their zinc complexes were determined. The rate constants of reactions of zinc acetate coordination with the studied ligands depend on their stability in the reaction medium. The doubly protonated forms of ligands had higher quantum yields than the monoprotonated forms, which is probably due to the redistribution of electron density in tetrapyrrole macrocycles controlled by inductive effects.
