| 中文摘要: |
| 合成两个新的具有潜在应用价值的非线性光学(NLO)有机材料查尔酮(a,b),通过1H NMR、13C NMR、IR、HR-MS表征其结构。采用4f 相位相干成像技术测定了a、b的三阶NLO性质,确定了相关参数: 脉冲宽度4 nm,激光波长分别为500nm 和440 nm,a: β = 7.3×10-10 m/W, n2 =- 3.6×10-17 m2/W, χ(3) = 2.56×10-11 esuS; b: β = - 4.8×10-10 m/W, n2 =2.0×10-17 m2/W, χ(3) = 1.45×10-11 esu；并测定了紫外光谱和DSC曲线。采用密度泛函方法计算了a、b的轨道能量和极化率,结果表明电子转移能在分子内部进行,显示出良好的非线性光学活性。 |
| 英文摘要: |
| Two nonlinear optical (NLO) organic materials—chalcone derivatives (a and b) were synthesized and characterized by 1H NMR,13C NMR, IR and HR-MS. Their third-order nonlinear optical properties were measured by 4f phase-coherent imaging system with pulse width 4 nm, laser wavelength 500 nm and 440 nm, respectively. The relevant parameters were given as follows: for compound a: β = 5.5×10-10 m/W, n2 = - 2.1×10-17 m2/W, χ(3) = 1.58×10-11 esu; for compound b: β = -2.4×10-10 m/W, n2 = 0.3×10-17 m2/W, χ(3) = 0.50×10-11 esu. The corresponding UV absorption and DSC curves were also investigated. Moreover, their orbital energy and polarization were calculated by density functional theory. The results indicate that the intramolecular electron transfer can occur. Thus they show good potential application as NLO materials. |
