Cyclometalated iridium(<scp>iii</scp>) polypyridine dibenzocyclooctyne complexes as the first phosphorescent bioorthogonal probes

Abstract

We report the synthesis, photophysical behavior, and biological properties of new cyclometalated iridium(iii) polypyridine complexes appended with a dibenzocyclooctyne (DIBO) moiety; these complexes have been utilized as the first phosphorescent bioorthogonal probes for azide-modified biomolecules.
