NITROGEN-CONTAINING AROMATIC COMPOUND AND METAL COMPLEX

摘要

PROBLEM TO BE SOLVED: To provide nitrogen-containing aromatic compounds with excellent oxygen reduction activity, metal complexes containing them, and catalysts and electrodes employing the same.

SOLUTION: The present invention provides an aromatic compound satisfying the following conditions (a) and (b): (a) it has two or more structures surrounded by at least four coordinatable nitrogen atoms (which structures may be the same or different); and (b) at least one of the nitrogen atoms composing the structure is a nitrogen atom in a six-membered nitrogen-containing heterocyclic ring.
