Synthesis of asymmetric tetraarylporphyrins and their ytterbium complexes

The synthesis of asymmetric meso -aryl-substituted porphyrins containing three 4-methoxycarbo-nylphenyl groups, and 4-hydroxyphenyl or 4-hydroxy-3-methoxyphenyl radicals or isomeric 3-and 4-pyridyl radicals as a forth substitute, is described. 4-Oxyalkyl derivatives are obtained. The ytterbium compl...

Description
Summary:The synthesis of asymmetric meso -aryl-substituted porphyrins containing three 4-methoxycarbo-nylphenyl groups, and 4-hydroxyphenyl or 4-hydroxy-3-methoxyphenyl radicals or isomeric 3-and 4-pyridyl radicals as a forth substitute, is described. 4-Oxyalkyl derivatives are obtained. The ytterbium complexes of these porphyrins have been synthesized, and their spectral luminescence properties have been studied. A significant difference in the lifetimes of the excited state of ytterbium complexes of the esters and acids of asymmetric porphyrins has been shown.
