Luminescent iridium(III) complexes have several appealing properties such as wide color-tunability and high photo- and chemical stabilities, whereas the properties of related diiridium(II) systems are largely unexplored. Here, the authors synthesize and characterize a series of tetracationic dinuclear iridium(II) complexes, which feature unsupported Ir(II)–Ir(II) single bonds and exhibit photoluminescence in various media.
