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。
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 Eu2L3（NO3）3（L = C11H12N3O3S） by chemical and elemental analysis, I H NMR, IR, mass spectrometry, laser Raman and three-dimension fluorescene spectrometry. The main fluorescence emission of the complex was Eu^3 ＋ perturbation ligand to light- emitting, along with the Eu^3＋ center narrow-band luminescence. When the λex = 330. 0 nm, the Eu^3＋ ion narrow-band fluorescence is emitted; when λex =410. 0 nm, the Eu^3＋ produces the 525.0 nm emission band.
