Self-assembly of a linear multicomponent porphyrin array through axial coordination

Abstract

The bis[4′-(4‴-pyridyl)-2,2′:6′,2″-terpyridine]ruthenium and osmium complexes 1a and 1b react with 2 equiv. of [Ru(TTP)(CO)(EtOH)] 4 to generate linear multicomponent arrays 3a and 3b; intramolecular phosphorescence quenching is observed for both arrays in contrast to their molecular building blocks which phosphoresce.
