Isoporphyrins. Near-Infrared Dyes with Noticeable Photochemical and Redox Properties

Abstract
An isoporphyrin prepared by the action of dibenzoyl peroxide on 5,10,15,20-tetraphenylporphinatozinc(II) (ZnTPP) shows absorption bands in the near-infrared region, is photolyzed to afford ZnTPP, and is facilely reduced by amines to ZnTPP.
