Abstract

The alternation of pi-bond orders of cyclacenes has been investigated within the framework of Huckel molecular orbital theory (HMO). It has been found that, depending on the number of arenoid rings present the pi-bond orders and the lengths in laticyclic and longicyclic parts of the cyclacene structures vary in opposite manner.
