| Abstract: | A novel monomer, viz., bipyridyl-containing dicarboxylic acid, was synthesized from 6-pyridyl-3,4-pyridine dicarboxylic acid anhydride and 5-aminoisophthalic acid. Novel polymer macroligands, viz., copolyamides containing 5, 15, 30, and 45% of the bipyridyl side groups, were obtained based on this monomer by low-temperature polycondensation. Metal polymer complexes (MPC) with different Ir(ppy)2 content were synthesized by the reaction of the polymer ligand with the binuclear complex [Ir(ppy)2Cl]2 (ppy is 2-phenylpyridine) and their properties were studied. |
