Blue-shifting the monomer and excimer phosphorescence of tridentate cyclometallated platinum(ii) complexes for optimal white-light OLEDs
By using a tridentate N^C^N-coordinating ligand, the luminescence of a cyclometallated Pt(ii) complex can be shifted into the blue region, without the problematic drop-off in quantum yield observed for bidentate analogues. The combination of blue-shifted monomer and excimer allows white-emitting OLEDs with high colour rendering index to be produced.
