Construction of cyclic arrays of Zn-porphyrin units and their guest binding at the solid–liquid interface

Abstract

Cyclic arrays consisting of six zinc-porphyrin units are constructed by the supramolecular self-assembly of a dehydrobenzo[12]-annulene derivative having three zinc porphyrin units at the liquid/graphite interface. Binding with C₆₀ furnishes cyclic hexameric arrays of the complexes on the surface.
