| 中文摘要: |
| 合成两种新颖的含二茂铁基团的查尔酮衍生物：1-二茂铁基-3-(4-叔丁基苯基)丙烯酮(a)和1-二茂铁基-3-联苯基丙烯酮(b),经1H NMR、13C NMR、HR-MS对其结构进行了表征；测定了该两化合物的热力学性质；采用量子化学方法计算了它们的分子轨道能量和极化率,给出了轨道电子云图；采用紫外-可见吸收光谱和Z-扫描技术测定了其线性和非线性光学性质。结果表明：与原料相比,化合物a和b的紫外吸收明显增加,且b的吸收波长更长；化合物a和b均存在分子内电荷转移现象,表现出超快三阶非线性光学响应。 |
| 英文摘要: |
| Two novel chalcone derivatives, 1-ferrocenyl-3-(4-t-butylphenyl)acrylic ketone(a) and 1- ferrocenyl-3-biphenylyl acrylic ketone(b) were synthesized and characterized by 1H NMR, 13C NMR, HR-MS. The molecular orbital energy and polarizability were calculated by quantum chemistry method. The thermodynamic properties of the two compounds were determined.Their linear and nonlinear optical properties were investigated using UV-Vis absorption spectra and Z-scan measurements. The results indicated that the absorption increased significantly and the absorption wavelength of compound b is longer. Both compound a and b have intramolecular charge transfer and the ultrafast third-order nonlinear optical response was showed. |
