Developments in the metal chemistry of N-confused porphyrin

Since its discovery as a side product in acid catalyzed condensations in 1994, the metal chemistry of N-confused porphyrins has grown exponentially. Due to the location of an external nitrogen on the porphyrin skeleton, different binding modes are being discovered for N-confused porphyrin as compared to tetraphenylporphyrin. In this paper, the metal chemistry of N-confused porphyrin is discussed, reviewing coordination modes and literature on the metal complexes to date. (C) 2003 Elsevier B.V. All rights reserved.
