48824 nately between the pyrrolic rings, l\_, gives rise to a family of coplanar porphyrin vinylogs, the platyrins? Like the porphyrins,[m,n,m,n]platyrins (m and n = odd numbers) are conjugated tetraazaannulenes containing 4n + 2 a-electrons. Thus,they might be expected to be "aromatic"(diatropic).2
