Design of luminescent iridium(III) and rhenium(I) polypyridine complexes as in vitro and in vivo ion, molecular and biological probes
Iridium, Luminescence, Probes, Rhenium
Many luminescent transition metal polypyridine complexes display intense and long-lived triplet charge-transfer and intraligand transition emission with a large Stokes’ shift. These properties render them promising candidates as luminescent probes for ions, DNA, peptides, proteins and other biological entities. In this review article, we have summarised recent reports on ion, molecular and biological probes derived from luminescent rhenium(I) and iridium(III) polypyridine complexes. These complexes have been appended with different recognition moieties that interact with ions and biological molecules. The recognition is reflected by a change of spectroscopic and/or photophysical properties of the probes. The use of these complexes as cellular probes and imaging reagents has also been discussed.
