| 摘 要： | 以量子化学半经验方法PM3优化构型为基础,利用INDO/CI方法研究了嵌入1,3-方酸的苯螺旋共轭分子的电子光谱,同时利用INDO/CI-SOS程序计算了它们的二阶非线性光学系数βijk和βμ值,从而探索分子结构与电子光谱及非线性光学性质的关系.理论计算结果表明:在苯螺旋共轭分子中适当地嵌入方酸后,其二阶非线性光学系数增大.与苯螺旋共轭分子和1,3-方酸的比较表明,方酸环处于左端的体系有很好的二阶非线性光学性质,可能成为较好的光学材料.

| Abstract: | On the basis of geometry optimized by quantum chemical PM3 method, electronic spectrum of 1,3 squaric acid tumbled in benzene spiro conjugated molecules was discussed by INDO/CImethod. The second order optical susceptibilities βijk and βμ of benzene spiro-conjugated molecules tumbled with 1,3-squaric acid were calculated by INDO/CI-SOS program. Theoretical calculation shouled that 1,3-squaric acid was tumbled in benzene spiro-conjugated molecules properly that made its second order optical susceptibilities increase. Compared with benzene spiro-conjugated molecule and 1,3-squaric acid, squaric acid that was tumbled in left bears better nonlinear optical property and possibly becomes a nice optical material. |
