Novel N6 trisbidentate ligand coordinated Ir(iii) complexes and their Ru(ii) analogs†
Abstract
Novel N6-coordinated Ir(III) complexes bearing polypyridyl ligands were synthesized and characterized. In comparison to their Ru(II) analogs, these Ir(III) complexes showed blue-shifted UV-vis absorption and emission spectra, but dramatically increased triplet lifetimes with much broader and stronger triplet excited-state absorption.
