根据Hǔckel运用分子轨道法研究单环共轭多烯的π电子能级!提出平面单环π体系呈现芳香性,其π电子数目必须是4n+2。此即为判别化合物芳香性的Huckel规则。此规则不仅适用于苯系化合物,对非苯π共轭体系也同样适用。

According to Höckel, the π electron energy level of monocyclic conjugated polyene was studied by molecular orbital method. It was proposed that the planar monocyclic π system is aromatic, and the number of π electrons must be 4n + 2. This is Huckel’s rule that determines the aromaticity of a compound. This rule applies not only to benzene compounds, but also to non-benzene π conjugated systems.
