Abstract
The paper presents the results of spectrophotometric study of the basic properties of glycosylated substituted derivatives of 5,10,15,20-tetraphenylporphyrin, namely 5-(4′- O -galactosylphenyl)-10,15,20-tris( N -methylpyridin-3-yl)porphine, 5,15-bis(4′- O -galactosylphenyl)-10,20-bis( N -methylpyridin-3-yl)porphine, 5,10,15,20-tetra( N -methylpyridin-3-yl)porphin, 5,10,15,20-tetra(4- O -galactosylphenyl)porphin. The basic properties of the studied ligands in acetonitrile at 298 K were studied by spectrophotometric method. The effect of glycosylated fragments, as constituents of a macromolecule, on protolytic equilibria during acid-base interactions of the ligand in basic media and the change in the reactivity of porphyrin ligands depending on the nature of the peripheral substituent was analyzed.
