摘要:
By using a tridentate N boolean AND C boolean AND 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.
