How low can you go? The [Pt–C,N,N] 2 moiety of the titled complexes are tethered by the rigid xanthene unit, which is selected to preclude excited states involving intramolecular metal–metal interactions, while allowing offset π‐stacking interactions, and this has pushed the associated excimeric‐type emissions into the near‐infrared region (see figure).
