Synthesis and Some Properties of Transition Metal Complexes with Octa(sulfophenyl)tetrapyrazinoporphyrazine

摘要

Sulfonation of metal complexes of octaphenyltetrapyrazinoporphyrazine gave water-soluble octa-sulfoderivatives.The complexes synthesized were studied by EPR,~1H NMR,electronic,and IR spectroscopy.It was found that,unlike complexes of other porphyrins and porphyrazines,this nickel complex is paramagnetic,whereas the cobalt complex gives no EPR signal.The cobalt complex can reversibly bind an oxygen molecule.
