The molecular orbital energy and polarizability were calculated by quantum chemistry method. The thermodynamic properties of the two compounds were determined.Their linear and nonlinear optical properties were investigated using UV-Vis absorption spectra and Z-scan measurements. The results indicated that the absorption increased significantly and the absorption wavelength of compound b is longer. Both compound a and b have intramolecular charge transfer and the ultrafast third-order nonlinear optical response was showed. 查看全文查看/发表评论下载PDF阅读器 相关附件：附件1附件2附件3版权转让声明书 -->
