摘要: 用INDO系列方法对由(C59N)2和苯甲醚合成的衍生物C59(C6H4OCH3)N进行了理论研究,得到了分子的稳定构型.结果表明,C59(C6H4OCH3)N具有Cs对称性.以优化构型为基础讨论了分子的UV-Vis光谱、NMR谱线数,结果与实验符合得很好.本文还计算了C59(C6H4OCH3)N的二阶非线性光学系数βμ,结果表明这种物质具有较大的二阶非线性光学系数.

关键词: C59(C6H4OCH3)N, UV-Vis光谱, 二阶非线性光学系数

Abstract: We have made theoretical research on the substituted azafullerene C59 (C6H4OCH3)Nsysthesised from (C59 N)2 and to anisole with the INDOseries methods. The stable molecular configuration of C59 (C6H4OCH3)N has been obtained, and C59 (C6H4OCH3)Nis Cs symmetry. On the basis of the obtained geometry, the UV Vis and NMRspactra of C59 (C6H4OCH3)Nhave been calculated and discussed. The results are in good agreement with experimental results. The nonlinear second order optical susceptibility βμ of C59 (C6H4OCH3)Nhave been calculated too. The result shows that this molecule has a quite big nonlinear second order optical susceptibility.

Key words: C59(C6H4OCH3)N, UV-Vis spectra, Nonlinear second-order optical property
