设计合成了2-(N'-乙基咔唑-3'-烯基)-8-羟基喹啉. 以UV-Vis, 1H NMR, FT-IR, 元素分析和MS进行了结构表征, 并测定了产物的光致发光(PL)性质. 运用Gaussian98量子化学程序包, 采用B3LYP密度泛函(DFT)的方法, 在6-31G(d,p)水平上对分子的几何构型进行结构优化; 预测目标产物的振动光谱, 结果表明与实验值相符.

关键词: 2-(N'-乙基咔唑-3'-烯基)-8-羟基喹啉, 光致发光, 振动光谱

N-Ethyl-3-[2-(8-hydroxyquinolin-2-yl)vinyl]carbazole have been synthesized and identified by UV-Vis, 1H NMR, FTIR, MS spectra and elemental analyses. Its photoluminescence properties were measured on an F-250 spectrometer. The geometry structure was optimized and vibration spectrum was predicted by the density functional theory calculations with the B3LYP functional on the level of 6-31G(d,p) basis set. The vibration spectrum predicted was compared with the observed value to be in good agreement.

Key words: N-ethyl-3-[2-(8-hydroxyquinolin-2-yl)vinyl]carbazole, vibration spectrum, photoluminescence
