Topological properties of altan-benzenoid hydrocarbons

Abstract

The main topological characteristics of altan-benzenoids are established. In particular, it is shown that the perimeter of Kekuléan altan-benzenoids is of size 4k , having a destablizing (antiaromatic) energy effect, similar to (4k)-annulenes.
