Recent developments in heteroporphyrins and their analogues

Abstract

Monoheteroatom substituted porphyrins and diheteroatom substituted porhyrins resulting from the replacement of one and two nitrogen atoms, respectively, are very stable aromatic molecules possessing very interesting properties. Significant progress has been made in last 5-6 years by developing newer methods and also by modifying the existing synthetic methodologies. These have been used to synthesize several heteroanalogues of porphyrins and their derivatives including the synthesis of chlorins, corroles, confused porphyrins, covalent and non-covalent porphyrin assemblies. This article reviews the developments that have been occurred in heteroporphyrin chemistry during 1999-2005. © 2005 Elsevier B.V. All rights reserved.
