【摘要】 在甲醇中合成了2-乙酰基苯并咪唑缩牛磺酸Schiff碱型配体及其与Eu(Ⅲ)的配合物。通过Eu化学和元素分析、质谱、核磁共振谱、红外光谱、激光拉曼光谱、三维荧光光谱,确定了配体与配合物的组成及结构。Eu(Ⅲ)配合物为Eu2L3(NO3)3(L=C11H12N3O3S)。配合物荧光发射主要是Eu3+微扰的配体发光,其次为中心Eu3+离子的窄带发射。当λex=330.0 nm时,配合物发射Eu3+离子的特征窄带荧光;当λex=410.0 nm时,Eu3+发射λem=525.0 nm的荧光。更多还原

【Abstract】 The Eu(Ⅲ) complex and new Schiff base ligand of taurine and 2-acetylbenzimidazole were synthesized in methyl alcohol.The structure of the complex was determined as Eu2 L3(NO3)3(L =C11 H12 N3 O3 S) by chemical and elemental analysis,1H NMR,IR,mass spectrometry,laser Raman and three-dimension fluorescene spectrometry.The main fluorescence emission of the complex was Eu3+ perturbation ligand to light-emitting,along with the Eu3+ center narrow-band luminescence.When the λex=330.0 nm,the Eu3+ ion narrow-band fluorescence is emitted;when λex=410.0 nm,the Eu3+ produces the 525.0 nm emission band.更多还原
