  Photophysical and Electroluminescent Properties of PtAg₂ Acetylide Complexes Supported with meso- and rac-Tetraphosphine

  摘要：

  1,2-Bis[adiphenylphosphino)methyn(phenyl)phosphinolethane (dpmppe) was prepared as, a new tetraphosphine, and the corresponding rac and meso stereoisorners were successfully separated in view of their solubility difference in acetone. The substitution of PPh3 into Pt(PPh3)(2)(C CR)(2) (R = aryl) with rac- or meso-dpmppe gives Pt(rac-rdprnppe)(C CR)(2) or Pt(meso-dpmppe)-(C CR), respectively. Using Pt(rac-dpnippe):(C CR)(2) or Pt(mesodpmppe)(C CR)), as a precursor, PtAg2 heterotrinudear duster complexes were synthesized and characterized by X-ray crystallography. Depending on the conformations.- of tetraphosphine, the structures of PtAg2 complexes supported with rac- and meso-dpmppe are quite different. The higher molecular rigidity of rac-dpmppe-supported PtAg2 complexes results in stronger phosphorescent emission than that of PtAg2 species, with meso-dpmppe. The high phosphorescent quantum yields (as high as 90.5%) in doping films warrant these PtAg2 complexes as excellent phosphorescent dopants in organic light-emitting diodes (OLEDs). The peak current and external quantum efficiencies, in solution-processed OLEDs are 61.0 cd A(-1) and 18.1%, respectively. Electroluminescence was elaborately modulated by modifying the substituient in aroinatic acetylide and the conformations in tetraphosphine so as to achieve cyan, green, green-yellow, yellow, and orange-red emission.

  摘要：

  通过膦交换反应合成了一系列具有三甲氧基苯基和咔唑基团的发光面对面的双核铂（Ⅱ）炔基膦配合物。还已经合成了两种混合金属四核铂（II）-银（I）和-铜（I）配合物。配合物的特征在于1 H，13 C和31P NMR光谱，阳离子FAB质谱，IR光谱和元素分析。它们中的大多数已通过X射线晶体学进行了结构表征。发现所有复合物均显示出发射行为。已经建立了发射性质与Pt···Pt距离，炔基和桥接膦配体的性质以及在炔基配体上包封的金属离子的性质的相关性。已进行TDDFT / CPCM计算，以提供对吸收和发射特性起源的进一步了解。
