Abstract

Chemical hybrids of the porphyrins and calixpyrroles, calix-[n] phyrins, are polypyrrolic macrocycles that contain at least one sp3 hybridized meso-like bridging carbon atom. While examples of calix [4] phyrin derivatives, represented by such classic structures as the phlorins, 1 isoporphyrins, 2 5, 10-or 5, 15-dihydroporphyrins, 3 and porphomethenes, 4 abound, the chemistry of higher order calix-[n] phyrins (n> 4) remains virtually unexplored. ...
