酚基嘧啶铍(Ⅱ)配合物的合成及光电性质
Synthesis and Photo-electricity Properties of Hydroxyphenyl-pyrimidine Beryllium(Ⅱ) Complex
摘要
Abstract
A novel chelating ligand 2-hydroxyphenyl-pyrimidine(HPP) was designed and synthesized through Suzuki coupling reaction. Its beryllium complex bis[2-(2-hydroxyphenyl) -pyrimidinato] beryllium[ Be( PP)2 ] was also prepared in high yields and characterized by IR and 'H 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)2as 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 FEclairage(CIE) color coordinates of (0.37, 0.39) and luminous efficiency of 0. 13 lm/W.关键词
