A giant M2L3 metallo-organic helicate based on phthalocyanines as a host for electroactive molecules

Abstract

An unprecedented Fe₂Pc₃ metallo-organic helicate has been assembled using a bidentate phthalocyanine (Pc) ligand, 2-formylpyridine and Fe(OTf)₂. This giant helicate has proved itself as a host for large redox-active guests such as fullerene and naphthalenediimide derivatives. Photoactivated electronic interactions between components occur in the host–guest complex.
