【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Eu2 L3( NO3)3(L=C11 H12N3O3S).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.%The Eu ( III ) complex and new Schiff base ligand of taurine and 2-acetylbenzinudazole were synthesized in methyl alcohol. The structure of the complex was determined as EU2L3(NO3)3( = C11H12N3O3S) 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 run, the Eu3+ ion narrow-band fluorescence is emitted; when λex =410.0 run, the Eu3+ produces the 525.0 nm emission band.
