Studies on porphyrin-quinhydrone complexes: Molecular recognition of quinone and hydroquinone in solution

Article abstract of DOI:10.1021/jo0100547

Free-base and zinc(II) porphyrins bearing either one, two, or four hydroquinone entities at the meso positions are shown to bind quinones in solutions via a quinhydrone pairing mechanism. Electrochemical studies reveal that the quinhydrone complexes are s
