Isomeric Double Decker Porphyrins Bridged by Four Azobenzene Units

Neumann, Karl Heinz,Voegtle, Fritz

, p. 520 - 522 (1988)

A novel macropentacyclic system (1) containing double layered porphyrin units which are bridged by four azobenzene links has been synthesized, two stable isomers being isolated, differing in spatial arrangement of the amide groups and azobenzene links; the complex formation of these compounds with zinc(II) is reported.
