从头

The equilibrium geometries of squaraines substituted by heteropentacyclic, benzo fuzed heteropentacyclic, heterohexacyclic, benzo fuzed heterohexacyclic, heptacyclic, benzo fuzed heteroheptacyclic and zwitterionic squaraines were obtained with ab initio calculation at HF/6-31G* level and the electronic spectra were examined using CIS/6-31G* method.

用从头算6-31G~*方法优化了多种五元杂环、苯并五元杂环、六元杂环、苯并六元杂环、七元环和苯并七元杂环取代的方酸分子以及方酸两性离子分子的几何结构；用CIS／6-31G~*方法计算了其电子光谱；通过TDHF／6-31G~*方法计算其线性极化率、一阶和二阶超极化率来研究分子结构和非线性光学性质之间的关系，同时用两态模型解释了部分分子的一阶超极化率。
