Abstract: The interesting emission properties of cyclometalated iridium(III) polypyridine complexes, originated from a range of excited states, have been well documented. The intense and long-lived emission of these complexes has been exploited in various areas of research including photovoltaic cells, chemosensors, and light-emitting devices. Additionally, there is an emerging interest in the applications of these luminescent complexes in various biological studies. In this paper, we summarize our recent work on the utilization of luminescent cyclometalated iridium(III) polypyridine complexes as biomolecular and cellular probes.
