Designing tridentate ligands for ruthenium(ii) complexes with prolonged room temperature luminescence lifetimes
Abstract
Coordination complexes have been used extensively as the photoactive component of artificial photosynthetic devices. While polynuclear arrays increase the probability of light absorption, the incorporation of the stereogenic Ru(2,2′-bipyridine)32+ motif gives rise to diastereomeric mixtures whereas the achiral Ru(2,2′:6′,2″-terpyridine)22+ motif creates stereopure polynuclear complexes. Thus, polynuclear arrays composed of ruthenium(II) complexes of tridentate
