“contamination” by visible light < 600 nm. This complex allows the fabrication of both yellow-green and deep red/NIR OLEDs; OLED emissions are in the yellow-green (CIE = 0.38, 0.56) and deep red/NIR (CIE = 0.65, 0,34) regions, for [PtL1Cl] 8 wt% (with 11% ph/e EQE) and pure [PtL1Cl] (with 4.3% ph/e EQE), respectively.
三种新型配合物[Pt(1,3-bis(4-triphenylamine-pyridin-2-yl)-4,6-difluoro-benzo)Cl]( [PtL 1 Cl] )、[Pt (1,3-双(4-
三苯胺-
吡啶-2-基)-5-
三苯胺-苯)Cl]( [PtL 2 Cl] ),和[Pt(1,3-双(4-
三苯胺-
吡啶-报道了2-基)-5-苯三甲基]( [PtL 3 Cl] )。它们都在稀释的脱气
二氯甲烷溶液中高度发光(Φ lum = 0.88-0.90,在黄绿色区域;单体的λ max,em以 nm 为单位为: [PtL 1 Cl]的 562、561和 549 ,[PtL 2Cl]和[PtL 3 Cl]分别)。[PtL 1 Cl]是最吸引人的,其特点是寿命很长 (103.9 μs),在浓缩脱气溶液 ( Φ lum = 0.66) 中显示出强烈的 NIR 发射,基本上没有可见光 < 600 nm
