摘　　要：合成一种新颖的D-π-A-π-D型双查尔酮衍生物4,4?-二[3-(芘-1-基)丙烯酰基]联苯,经IR、1H NMR、MS和元素分析对其结构进行表征.在波长为480 nm、脉宽为4 ns的激光脉冲激发下,应用4f相位相干成像技术测量了其三阶光学非线性性质,并测定了紫外光谱和DSC曲线.A novel chalcone derivatives, 4,4？-bis[3-（pyrene-1-yl）] propylene acyl diphenyl, was synthesized. And it was characterized by 1H NMR, IR, MS and elemental analysis. The third-order nonlinear optical（NLO） properties were measured by 4f phase-coherent imaging system and the resulting relevant parameters were given as following with pulse width 4 ns, laser wavelength 480 nm： β=-0.6×10-10 m/W, n2=-0.5×10-17 m2/W, χ（3）=1.0×10-20 C. The corresponding UV absorption and DSC curves were also investigated.
