Multimetallic porphyrin monomers

Abstract

Complexation of triosmium clusters to pyridyl functionalised metalloporphyrins gives heterometallic derivatives that possess the overall recognition and spectroscopic properties of the porphyrin fragment, while incorporating the electronic and structural characteristics of the cluster.
