Two luminescent iridium(iii) complexes, 1 and 2, were synthesized and evaluated for their ability to probe COX-2 in human cancer cells. This is the first application of iridium(iii) complexes as imaging agents for COX-2. We demonstrate that complex 1 differentiates cancer cells from normal cells with high stability and low cytotoxicity.
