Calculation of Topological Indices Based on the Distance of Polyacenes Without Edge Counting
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.
期刊介绍:
The purpose of Polycyclic Aromatic Compounds is to provide an international and interdisciplinary forum for all aspects of research related to polycyclic aromatic compounds (PAC). Topics range from fundamental research in chemistry (including synthetic and theoretical chemistry) and physics (including astrophysics), as well as thermodynamics, spectroscopy, analytical methods, and biology to applied studies in environmental science, biochemistry, toxicology, and industry. Polycyclic Aromatic Compounds has an outstanding Editorial Board and offers a rapid and efficient peer review process, as well as a flexible open access policy.
