| 中文摘要: |
| 合成一种双查尔酮衍生物：4,4′-二[3-(3,4-二甲氧基苯基) -2-丙烯酰基]联苯(BBPAB),经IR、1H NMR、13C NMR、LC-MS等分析测试手段对其结构进行了表征确认。测定了该化合物的DSC/TG曲线,表明该化合物热稳定性良好。测定了其紫外-可见光谱,在可见光范围有高的线性透光率。利用Z扫描测试方法研究了BBPAB在190 fs(515-700 nm)时域下的非线性光学吸收,实验发现在飞秒脉冲下具有宽波段的反饱和吸收性质,并拟合得到了三阶非线性吸收系数和五阶非线性吸收系数。量子化学计算结果表明,BBPAB存在较强的分子内电荷转移现象和较大的极化率。 |
| 英文摘要: |
| A novel double chalcone derivative, 4,4′-bis[3-(3,4-bimethoxy phenyl)-2-acryloyl] biphenyl(BBPAB) was synthesized, characterized and confirmed by IR、1H NMR、13C NMR、LC-MS and other analytical methods. The DSC/TG curves of BBPAB were determined, and the results showed that the thermal stability was good. The UV-Vis spectrum was measured, and there was a high linear transmittance in the visible range. The nonlinear absorption propertie of BBPAB was investigated under 190 fs (515-700nm) by Z-scan measurements. It was found that the BBPAB realized broadband reverse saturable absorption (RSA) under femtosecond excitation, and Third-order nonlinear absorption coefficient and fifth-order nonlinear absorption coefficient are obtained by fitting. Quantum chemical calculations indicated that There are strong transfer phenomena inside the molecule and larger polarizability of BBPAB. |
