From the UV spectra, it can be found that the aromaticity of acenaphthenyl groups in C_2 gum is the largest. But there are 30 carbon atoms in the conjugated structure of condensed aromatics in C_1 gum and C_3 gum, while 28 carbon atoms in acenaphthenyl groups in C_2 gum.

但是,在C_1胶、C_2胶和C_3胶三者中,C_1胶侧链上的四苯基苯基和C_3胶侧链上的菲式多苯基苯基都含有30个碳原子,而C_2胶侧链上的苊式多苯基苯基含有28个碳原子,比前面二者小2个碳原子,理应其芳香性在三者之中最小,但事实却恰恰相反。

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。

In order to improve the radiation resistance of condensed-type RTV silicone rubber, two kinds of crosslinking agents are synthesized successfully: triethoxysilane with acenaphthenyl groups m.p.

当三乙氧基硅烷和三乙氧基硅烷用作缩合型RTV硅橡胶的交联剂时,由于二者所含的稠环基团的空间位阻较大,因而样品硫化速度较慢。
