合成一种新颖的D-π-A-π-D型双查尔酮衍生物2,6-二[3-(4-甲氧基苯基)]丙烯酰基吡啶,经IR,~1H NMR和HR-MS对其结构进行表征,采用4f相位相干成像技术测定了它的三阶NLO性质并确定了相关参数:脉宽4ns,激光波长450nm,非线性吸收系数β=0.9×10~(-9) m/W,非线性折射率n_2=-0.42×10~(-16) m~2/W,三阶非线性极化率χ~((3))=4.10×10~(-19) m~2/V~2;并测定了紫外光谱和DSC曲线.
A novel bis-chalcone derivative 2,6-bis [3- (4-methoxyphenyl)] acryloylpyridine was synthesized and characterized by IR, ~ 1H NMR and Its structure was characterized by HR-MS. The third-order NLO properties were determined by 4f phase coherence imaging and the related parameters were determined: pulse width 4 ns, laser wavelength 450 nm, nonlinear absorption coefficient β = 0.9 × 10 -9 ) m / W, the nonlinear refractive index n_2 = -0.42 × 10 ~ (-16) m ~ 2 / W, the third order nonlinear polarizability χ ~ (3) = 4.10 × 10 ~ (-19) m ~ 2 / V ~ 2. The UV spectra and DSC curves were also measured.
