Sweetness and light: Sugar-functionalized CˆN and NˆN ligands in [Ir(CˆN)2(NˆN)]Cl complexes

Sweetness and light: Sugar-functionalized CˆN and NˆN ligands in [Ir(CˆN)2(NˆN)]Cl complexes
Sugars represent a readily available entry into the chiral pool and possess a multivalent functionality allowing specific functionalization for attachment to scaffolds possessing programmed properties. We report a series of cyclometallated iridium(III) complexes [Ir(CˆN)2(NˆN)][PF6] in which a photo- and redox-active iridium scaffold is functionalized with ribofuranose substituents. The localization of HOMO and LUMO character in different parts of the iridium core is retained in the conjugates and proof-of-concept compounds with the ribofuranose attached to the CˆN and NˆN ligands confirm that the photophysical and redox properties may be refined utilizing the well-established algorithms.
