合成了新的N-乙基咔唑衍生物: 3,6-二[2-(8-羟基喹啉基)乙烯基]咔唑(4)及其锌配合物(5); 化合物4经质谱、红外光谱、核磁共振氢谱、元素分析表征其结构, 并测定了它的荧光光谱. 结果显示: 化合物4的荧光发射为蓝绿色光(500 nm), 其发射光谱随着溶剂极性的增大荧光光谱向长波方向移动(即发生红移); 同时, 考察了化合物5的荧光性质, 其荧光发光峰值为600 nm, 与2-甲基-8-羟基喹啉锌相比, 发生了明显的红移.

3,6-Bis[2-(8-hydroxyquinolin-2-yl)vinyl]carbazole (4) and its Zn(II) complex 5 have been synthesized, and the former was identified by 1H NMR, FTIR, MS spectra and elemental analyses. Their photoluminescence properties were measured on an F-2500 spectrometer. The results show that compound 4 is green-emitting (500 nm) and the fluorescence spectrum is obviously red-shifted at room temperature. Meanwhile, the fluorescene properties were discussed. The emission peak of compound 5 is at 600 nm and shows obvious red-shift compared with 2-methyl-8-quinolinolato zinc complex.

Key words: 3,6-bis[2-(8-hydroxyquinolin-2-yl)vinyl]carbazole, fluorescence property, 2-methyl-8-hydroxyquinoline
