Iridium(III)-based chemosensors for the detection of metal ions.

In recent years, transition metal complexes with their prominent photophysical properties have emerged as versatile chemosensors to probe different target analytes, including metal ions. By incorporating specific metal ion receptors, various iridium(III) complex-based cation sensors have been developed using different mechanisms. In this review, we survey examples of iridium(III) complex-based metal ion chemosensors that have been reported in the literature. Their design, mechanism and outlook will also be discussed.

Iridium(iii) complexes as reaction based chemosensors for medical diagnostics.

Transition metal complexes have attracted interest in the fields of cancer therapy, medical and environmental detection, and materials of organic light-emitting diodes (OLED). Recently, iridium(iii) complexes have been explored in a reaction based way for luminescence monitoring and imaging due to their salient photophysical properties, including large Stokes shifts, long-lived luminescence and high luminescent quantum yields. This frontier article will introduce recent developments and applications of iridium(iii) complexes as luminescent probes for ions and biomolecules. Our outlook for this class of complexes is also discussed.
