Diiridium(<scp>iii</scp>) complexes: luminescent probes and sensors for G-quadruplex DNA and endoplasmic reticulum imaging

Abstract

Two new dinuclear iridium (Ir) complexes bridged by a conjugated aromatic tppz ligand, (bhq)₂Ir(tppz)Ir(bhq)₂(<bold>1</bold>) and (ppy)₂Ir(tppz)Ir(ppy)₂(<bold>2</bold>) (bhq = benzo(<italic>h</italic>)quinolone, ppy = phenyl-pyridine, tppz = tetrapyrido[3,2-<italic>a</italic>:2′,3′-<italic>c</italic>:3′′,2′′-<italic>h</italic>:2′′′,3′′′-<italic>j</italic>]phenazine), were prepared.
