摘要
Tridentate cyclometalated platinum(II) complexes bearing sigma-alkynyl ligands exhibit tunable photoluminescence and enhanced stability during vacuum deposition; OLEDs based on these materials display orange to red electrophosphorescence with low turn-on voltages (similar to4 V), maximum luminance approaching 10000 cd m-(2) and efficiency up to 4.2 cd A(-1).
