Platinum(II) Emitters

Terdentate heteroaromatic ligands offer great versatility for the development of Pt(II)-based luminescent materials, as they impart rigidity that reduces nonradiative deactivation while still leaving a coordination site available on the metal for excited-state modulation. This can be achieved through the introduction of monodentate ancillary ligands with different electronic and steric properties, or by employing polydentate bridging ligands to form polymetallic systems that may exhibit Pt···Pt metallophilic contacts and π–π interactions between the aromatic moieties. Although many Pt(II) complexes bearing heteroaromatic N∧N∧N, N∧C∧N, N∧N∧C, or C∧N∧C ligands have been reported, those incorporating N∧C∧C ligands were almost nonexistent until our recent work, in which we demonstrated a photochemical synthetic approach. This class of ligands displays key features that make them promising for the design of versatile and efficient Pt(II) emitters, as they provide strong σ-donation from the cis-disposed aryl groups and largely planar structures that facilitate aggregation phenomena.
