摘    要:采用Suzuki偶联方法合成了新型有机螯合配体酚基嘧啶(HPP), 利用HPP进一步合成了酚基嘧啶铍配合物Be(PP)2. 采用核磁共振(1H NMR)和红外(IR)光谱等方法对其结构进行了表征, 并通过测定紫外-可见(UV-Vis)和光致发光(PL)光谱对Be(PP)2的光学性质进行了研究. 结果表明, 配合物在460 nm处有最大发射. 以Be(PP)2为电子传输层和发光层制备了结构为氧化铟锡(ITO)/N,N'-二(萘-2-基)-N,N'-二(苯基)联苯-4,4'-二胺(NPB)(45 nm)/Be(PP)2(60 nm)/Al(300 nm)的双层模型器件, 获得了最大亮度为103 cd/m2的近白光发射, 色坐标为(0.37, 0.39), 光功率效率为0.13 lm/W.

关 键 词:酚基嘧啶铍  有机发光材料  白光电致发光器件

Abstract:A novel chelating ligand 2-hydroxyphenyl-pyrimidine(HPP) was designed and synthesized through Suzuki coupling reaction.Its beryllium complex bis2-(2-hydroxyphenyl)-pyrimidinato]berylliumBe(PP)2] was also prepared in high yields and characterized by IR and 1H NMR.Upon photoexcitation,the complex displayed intense blue emission(λmax=460 nm) in methanol solvent at room temperature.In addition,a white organic electroluminescent device was fabricated by vacuum thermal evaporation with a double-layer structure of indium tin oxides(ITO)/N,N′-bis(naphthalene-2-yl)-N,N′-diphenyl-1,1′-biphenyl]-4,4′-diamine(NPB)(45 nm)/Be(PP)2(60 nm)/Al(300 nm) using the Be(PP)2 as emitting and electro-transporting material.The non-doping device showed a lower turn-on voltage of 4 V,a maximum brightness of 103 cd/m2,a commission internationale de I’Eclairage(CIE) color coordinates of(0.37,0.39) and luminous efficiency of 0.13 lm/W.
Keywords:Hydroxyphenyl-pyrimidine beryllium  Organic luminescent material  White organic electroluminescent device
