摘　　要：合成一种新型化合物ω,ω,ω′,ω′-四溴-2,6-二乙酰基吡啶(TBDP),通过IR,1H NMR,13C NMR和HR-MS表征其结构.测定了紫外吸收光谱和荧光发射光谱.采用密度泛函理论方法计算了TBDP的分子轨道能量和极化率.在脉宽190 fs,激光波长480 nm条件下,采用Z-扫描技术测定了TBDP的三阶非线性光学折射系数n2=1.9×10-19 m2·W-1,表现出超快三阶非线性光学响应.A new organic compound,ω,ω,ω′,ω′-tetrabromo-2,6-diacetyl pyridine(TBDP),was synthesized and characterized by IR,1H NMR,13C NMR and HR-MS.Its UV absorption and fluorescence spectrum were also measured.Moreover,its orbital energy and polarization were calculated by density functional theory.The third-order nonlinear optical properties of TBOP were measured by Z-scan technique with 190 fs laser pulse at 480 nm and the resultant nonlinear refractive index n2 is 1.9×10-19 m2·W-1,which proves that the title compound TBDP can show ultrafast third-order nonlinear optical response.
