用AM1和ZINDO系列方法研究了以螺原子连接的立体交叉型分子的几何构型,研 究了各分子的稳定构型并以稳定构型为基础,计算了这些分子的电子光谱,二阶非 线性光学系数β_μ, β_0,考察了取代基变化对β_μ的影响。计算结果表明所设 计分子兼具较大的二阶非线性光学系数和较高的透过率,有希望成为一类新型的二 阶非线性光学材料。

The geometry structure, electronic spectra and nonlinear second- order optical properties of series of spiro-atom linked three- dimensional molecules were investigated using AMl and ZINDO series method. The relationship between the nonlinear second-order optical properties of studied molecules and their substitutes was discussed. The calculated results show that these molecules have high transparence as well as large nonlinear second-order optical susceptibilities.
