摘　　要：设计合成了一种新型的配体[5-(1,3-二苯基吡唑)基]-8-羟基喹啉(PyQ),并利用元素分析、傅立叶变换红外光谱(FTIR)、核磁(1H NMR)和质谱(MS)等方法对其结构进行了表征;利用配体PyQ良好的配位能力,制备了新型的稀土配合物Ln(PyQ)3(RE=Yb^3+, Nd^3+),并对其发光性能进行了初步研究,结果表明:制得的配合物均可在可见光激发下得到相应的稀土离子的特征发光,最大激发波长为468 nm。A novel 8-hydroxyquinolin derivative [5-(1,3-diphenyl-4,5-dihydro-1 H-pyrazol-4-yl)quinolin-8-ol](denoted as PyQ) was designed and synthesized. The resulted ligand PyQ was characterized by 1H NMR, MS and elemental analysis. Two new rare earth complexes RE(PyQ)3(RE=Nd^3+, Yb^3+) were prepared using PyQ as the ligands, and their photoluminescence properties were studied. The results showed that the RE(PyQ)3(RE=Nd^3+, Yb^3+) complexes exhibited the characteristic near-infrared emission of the Nd^3+ and Yb^3+ ions under excitation of visible light, respectively, and the maximum excitation wavelength was 468 nm.
