Abstract

A new graphene pattern, called CorSu, was designed by combining the patterns of coronene [6:66]
and sumanene [6:(5,6)3]. The energy of some small fragments of this lattice, functionalized by groups
containing oxygen, carbon, nitrogen and phosphorus, was evaluated at the level of semiempirical method
PM3. The topology of the network is described in terms of Omega counting polynomial. Close formulas
for calculating the Omega polynomial and the Cluj-Ilmenau index derived from this polynomial are given.

Keywords
