【摘要】 在甲醇溶液中合成了新型2-乙酰基苯并咪唑缩牛磺酸Schiff碱配体及其铽(Ⅲ)配合物,通过元素分析、质谱、核磁共振谱、红外光谱、三维荧光激发和发射光谱进行了分子组成确证及性质研究.结果表明,铽(Ⅲ)配合物组成为Tb2L3(NO3)3(L=C11H12N3O3S),该配合物的荧光除受中心离子微扰的配体发光外,还有明显的中心Tb3+离子窄带发射,在220.0~350.0 nm(最佳激发波长为320.0 nm)激发时,发射中心Tb3+离子的特征窄带荧光;在350.0~540.0 nm(最佳激发波长为410.0 nm)激发时,产生550.0 nm的发射谱线;在波长为860.0 nm的锐光激发下,发射490.0 nm的上转换荧光.

【Abstract】 The terbium(Ⅲ) complex and a new Schiff base ligand by 2-acetylbenzimidazole and taurine have been synthesized in methyl alcohol solution.Their structures and properties are confirmed by element analysis,mass spectrometry,IR spectra,1HNMR spectra,three-dimensional fluorescence excitationand emission spectra.The results show that the composition of Tb(Ⅲ) complex is Tb2L3(NO3)3(L=C11H12N3O3S).Fluorescence of the complex in addition to the ligand luminescence which perturbed by the center of Tb3+ ion,there is obviously the Tb3+ ion narrow-band emission.At 220.0~350.0 nm(the optimal excitation wavelength is 320.0 nm)excitation light,the characteristics of Tb3+ ion narrow-band fluorescence is emitted;at 350.0~540.0 nm excitation zone(the best excitation wavelength is 410.0 nm),the complex is stimulated to produce a wavelength of 550.0 nm emission spectrum;in the sharp light of 860.0 nm excitation,it emits 490.0 nm up-conversion fluorescence.
