Sensitized near infrared emission through supramolecular d→f energy transfer within an ionic Ru(II) – Er(III) pair

Abstract

The newly synthesized ionic triple salt Ru-Er, {[RuII(bpy)2(dbim)][ErIII(hfac)4][CF3COO]•H2O} (bpy = 2,2’-bipyridine; hfac- = hexafluoroacetylacetonate; dbim = 2,2'-dibenzimidazole) exhibits near-infrared (NIR) emission at 1535 nm by intermolecular Ru→Er (d→f) energy transfer across supramolecular interactions when pumped within the Ru(II) 3MLCT band. It is the first such observation for a transition metal-lanthanide ionic pair.
