A Double-Twist Möbius-Aromatic Conformation of [14]Annulene

B3LYP and KMLYP/6-31G(d) calculations predict a double-helical and chiral conformation of [14]annulene with the topological properties of
a double-twist Möbius band as highly aromatic; its energy with respect to the known Hückel-aromatic conformation is predicted to be stabilized
by suitable ring substitution.

采用B3LYP与KMLYP/6-31G(d)方法进行的量子化学计算预测，[14]轮烯存在双螺旋手性构象，该构象具备双扭莫比乌斯带（double-twist Möbius band）的拓扑特性且呈现高度芳香性；相较于已知的休克尔芳香性构象，该构象的能量可通过合适的环取代实现稳定化。
