英文摘要利用 2 ,3 -二苯基吡嗪与水合三氯化铱反应合成了一种新型吡嗪铱的配合物 [Ir( dphp) 2 ( acac) ],通过元素分析 ,1 H NMR和 MS对配合物结构进行了表征 ,并研究了配合物的吸收光谱和光致发光光谱 .利用该材料作为磷光染料制备了结构为 [ITO/ NPB( 3 0 nm) / NPB∶ 8%[Ir( dphp) 2 ( acac) ]( 2 5 nm) / PBD( 1 0 nm) /Alq3( 3 0 nm) / Mg∶ Ag(质量比 9∶ 1 ) ( 1 3 0 nm)的电致发光器件 ,研究了其电致发光光谱 .结果表明 ,该配合物在 3 93和 5 2 8nm处...; A new iridium pyrazine complex, [Ir(dphp)(2)(acac)](dphp=2, 3-diphenylpyrazine, acac= acetylacetone), was synthesized by reaction of diphenylpyrazine with iridium trichloride hydrate. The complex was characterized by elemental analysis, H-1 NMR, and mass spectroscopy. The UV-Vis absorption and photoluminescence of the complex were investigated. The complex shows strong (MLCT)-M-1(singlet metal to ligand charge-transfer) and (MLCT)-M-3(triplet metal to ligand charge-transfer) absorption at 393 and 528 nm, respectively. Organic light emitting diodes(OLEDs) with a configuration of ITO/NPB(30 nm)/NPB : 8% [Ir(dphp)(2)(acac)](25 nm)/PBD(10 nm)/Alq(3)(30 nm)/Mg : Ag(mass ratio 9 : 1) (130 nm) were fabricated by using this complex as the triplet emissive dopant in NPB. The diodes showed an external quantum efficiency of 13.85% at 6.5 V and brightness of 11 478 cd/m(2) at 10 V. The power efficiency of the device was 15.54 lm/W at 6.5 V, indicating that this complex is a promising electrophosphorescent materials.; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 13; 03; 397-400+388; 25
