Complexation and Basic Properties of Polyethylene Oxide-Substituted Porphyrins

摘要

Basic properties of bis[5-(3-oxyphenyl)-2,8,12,18-tetrabutyl-3,7,13,17-tetramethylporphyrinyl]-3,6,9-trioxyundecane-1,11 and bis[5-(3-oxyphenyl)-2,8,12,18-tetrabutyl-3,7,13,17-tetramethylporphyrinyl]-3,6,9,12-tetraoxytetradecane-1,14 were studied spectrophotometrically in an ethanol-sulfuric acid system; the influence of the basicity of the inner cycle nitrogen atom on the complexation properties of these polyethylene oxide-substituted porphyrins towards zinc cation in ethanol was considered.
