Cyclometalated Iridium (III) complexes: Recent advances in phosphorescence bioimaging and sensing applications

Abstract

The phosphorescence bioimaging and sensing applications of Iridium (III) complexes, in particular to subcellular organelle staining as well as sensing of biologically important analytes, have been reviewed here. The bioimaging applications of the metal complexes provide an attractive alternative to fluorescent organic compounds in the construction of biosensors and biolabels because of having certain advantages.
