carbonyl complexes with the formula [Re(CO)(3)(L)Br], where L = 1-(4-5'-phenyl-1,3,4-oxadiazolylbenzyl)-2-pyridinylbenzoimidazole (1) and 1-(4-carbazolylbutyl)-2-pyridinylbenzoimidazole (2), have been successfully synthesized and characterized by elemental analysis, (1)H NMR, and IR spectra. Their electrochemical, photophysical, and electroluminescent behaviors, along with the X-ray crystal structure analysis
两个具有式[Re(CO)(3)(L)Br]的新型二亚胺rh(I)羰基配合物,其中L = 1-(4-5'-苯基-1,3,4-恶二唑基苄基)-2-吡啶基苯并咪唑(1)和1-(4-咔唑基丁基)-2-吡啶基苯并咪唑(2)已成功合成并通过元素分析,(1)NMR和IR光谱进行了表征。还介绍了它们的电化学,光物理和电致发光行为,以及2的X射线晶体结构分析。使用1和2作为发射器制造了白色电致磷光器件。基于结构为ITO / m-MTDATA(30 nm)/ NPB(20 nm)/ 2:CBP(8%,30 nm)/ Bphen(20 nm)/ Alq(3)(20 nm)/ LiF(0.8 nm)/ Al(200 nm)表现出国际照明委员会坐标x = 0.34,y = 0。33在580 mA / cm(2)时的最大亮度为2300 cd / m(2)。当在230 mA / cm(2)处出现1500 cd / m(2)的亮度时,基于10
