Cyclometalated Iridium(III) Bipyridine Complexes Functionalized with anN-Methylamino-oxy Group as Novel Phosphorescent Labeling Reagents for Reducing Sugars

Cyclometalated iridium(III) bipyridine complexes appended with an N-methylamino-oxy group have been developed as phosphorescent labeling reagents for reducing sugars; the emission behavior, reactivity, cytotoxicity, and cellular uptake of these iridium(III) complexes and their sugar conjugates have been investigated.
