So, the aromaticity of acenaphthenyl groups in C_2 gum should be the least. In order to explain the reason, quantum chemical calculation is utilized. The optimized geometrical structrures of condensed aromatics in C_1 gum, C_2 gum and C_3 gum are calculated at B3LYP/6-31G* levels. We find that some phenyl groups in acenaphthenyl groups are coplanar and have the largest conjugated structure.

为了解释其原因，我们利用量子力学方法进行了计算，研究了三种稠环基团在B3LYP／6-31G*基组水平下优化得到的几何结构，发现苊式多苯基苯基中的萘环和中间的苯环共面，电子离域性最大，而其他二者所有苯环都不共面，发生了明显地扭曲；同时，在优化几何结构的基础上，对三种化合物进行了前线分子轨道的分析，利用密度泛函理论方法(density function theory，DFT)计算了稠环基团的最高占有轨道和最低未占轨道之间的能量差，即能隙，发现C_2胶上苊式多苯基苯基的Eg最小，解释了C_2胶具有最好的辐射保护效果的原因。
