稠环芳烃的化学通式以及其芳香性与休克尔规则的关联

General Chemical Formula of Polycyclic Aromatic Hydrocarbons and Relationship between their Aromaticity and Hückel Rule

为了阐明稠环芳烃的芳香性,通过一个简单的数学模型推导出稠环芳烃的分子通式为C4R＋2-IH2R＋4-I。以此分子通式外推则可以很好地解释为什么任意一个稠环芳烃均符合4n＋2的休克尔规则,并且其中n=R-I/2。利用数学模型得到的这个分子通式提供了一种新的理解芳香性问题的科学思路。

To elaborate the aromaticity of polycyclic aromatic hydrocarbons （PAHs）, this ar- ticle constructed a simple mathematic model to deduce their general formula as C4n＋2-I H2R＋4-I. Extrapolation of this formula can explain well why every PAH compound follows the （4n＋2） Huckel rule while the n equals （R-I/2）. This formula provides a new scientific understanding to aromaticity from the reinterpretation of mathematics.
