Abstract

The number of Kekulé structures is an indicator of the aromatic character of the underlying polybenzenoid. Graphite is a polybenzenoid. In this paper, a new algorithm is proposed for determining the number of Kekulé structures in rectangular graphite and its incomplete and defective variants. Defective patterns model functionalized structures. Moderate functionalization will cause a slight increase in the aromatic properties of the underlying patterns.
