| 摘要: 合成并通过单晶衍射表征了3个配合物[CuLCl2]·CH3CN(1)，[CuLBr2]·CH3CN(2)和[ZnL(NO3)2]·CH3CN(3)(L=2-(5-氯-8-喹啉氧基)-1-(吡咯烷-1-基)乙酮)。在配合物1和2中，五配位的铜离子采取扭曲的四方锥配位构型，与来自配体L的2个氧原子和1个氮原子及2个卤离子配位。而在配合物3中，锌离子与1个三齿配位的配体L，1个单齿配位的硝酸根和1个双齿配位的硝酸根配位，配位构型为扭曲的八面体。乙腈溶液中，配合物1和2在410 nm处的最大荧光发射峰与配体L的相似，强度有所降低。而配合物3由于配体到锌离子之间的能量转移，最大荧光发射峰红移至430 nm。 | |

| Abstract: Three complexes,[CuLCl2]·CH3CN (1),[CuLBr2]·CH3CN (2) and [ZnL(NO3)2]·CH3CN (3) (L=2-(5-chloroquinolin-8-yloxy)-1-(pyrrolidin-1-yl)ethanone), were synthesized and characterized by X-ray diffraction. In each of complexes 1 and 2, the five-coordinated Cu(Ⅱ) ion is in a distorted tetragonal pyramid with a NO2 donor set from one ligand L and two halide anions. However, the Zn(Ⅱ) ion in complex 3 is surrounded by one tridentate ligand L and two nitrate anions, one of which is monodentate and the other is bidentate, thus giving distorted octahedral coordination geometry. In CH3CN solution, complexes 1 and 2 exhibit similar peak at 410 nm as that of the ligand L, while with a decrease of the fluorescence intensity. However, the emission band of complex 3 red-shifts to 430 nm because of energy transferring from the ligand L to the Zn(Ⅱ) ion. | |
