Abstract
Acenes or polyacenes are a group of organic compounds and polycyclic aromatic hydrocarbons consisting of benzene rings that are linearly fused. They are also the building blocks of nanotubes and graphene and follow the general molecular formula Due to the applications of polyacenes in optoelectronics, they are interesting for chemical and electrical engineering researchers. In this article, the general formulas for distance-based topological indices of Szeged, Mostar, and Padmakar-Ivan are determined by SMP-polynomials, which do not require edge counting and this formula work only by having the number of benzene rings in the composition of polyacenes.
