Cyclometalation of a triple helical N‐doped phenylene cage prepared by ruthenium(0)‐catalyzed diol–diene benzannulation delivers a chiral, conformationally constrained Ir(ppy) 3 analogue. Like the parent complex, fac ‐Ir(ppy) 3 , the iridium‐containing PAH‐cage is phosphorescent, but displays enhanced resistance to oxygen quenching.
