The synthesis of water-soluble hemiporphyrazine analogues
摘要:
The synthesis of a new class of water-soluble tetradentate macrocyclic complexes is reported. A hemiporphyrazine derivatized with pyridine groups about the periphery has been prepared. The copper(II) and nickel(II) complexes were synthesized from the free-base ligand. The peripheral pyridine groups of the free ligand and the metal complexes have been methylated to yield complexes exhibiting appreciable water solubility. Visible absorption spectra and cyclic voltammetric data are reported.
