crossing the spectrum of visible light. Most of the Pt complexes are strongly luminescent (Φ = 0.32−0.63) and have short luminescence lifetimes (τ = 4−7 μs) at room temperature. The lowest excited state of the Pt(N∧C∧N)X complexes is identified as a dominant ligand-centered 3π−π* state with some 1MLCT/3MLCT character, which appears to have a larger 1MLCT component than their bidentate and tridentate analogs
