| 摘 要： | Abstract The 2-acetyl-benzimidazoledehyde-glycine Schiff-base ligand and the corresponding Pr（Ⅲ） complex Pr2L3（NO3）3· 2CH3OH （L=C11H10N3O2） were synthesized in methanol and characterized by a series of methods, including chemical analysis, elemental analysis, TOF-MS, ^1H NMR, UV-, IR-, Raman spectra, thermal analysis, and the three-dimension fluorescence excitation and emission spectra. The Pr（Ⅲ） complex exhibits extraordinary water-solubility and the Pr（Ⅲ） hydroxide appears at pH≥13. The complex also possesses specific fluorescent properties. Thus, at the excitation wavelengths 200.0-280.0 and 260-350 nm the fluorescence bands were observed at 290.0 and 400.0 nm, respectively.

| Abstract: | The 2-acetyl-benzimidazoledehyde-glycine Schiff-base ligand and the corresponding Pr(III) complex Pr2L3(NO3)3) · 2CH3OH (L=C11H10N3O2) were synthesized in methanol and characterized by a series of methods, including chemical analysis, elemental analysis, TOF-MS, 1H NMR, UV-, IR-, Raman spectra, thermal analysis, and the three-dimension fluorescence excitation and emission spectra. The Pr(III) complex exhibits extraordinary water-solubility and the Pr(III) hydroxide appears at pH ⩾ 13. The complex also possesses specific fluorescent properties. Thus, at the excitation wavelengths 200.0–280.0 and 260–350 nm the fluorescence bands were observed at 290.0 and 400.0 nm, respectively. |
