Abstract:

Coro-graphene is a two-dimensional carbon-based material with a narrow band gap. It has intriguing electronic characteristics that are more susceptible to external strain and doping, thereby making them an excellent choice for nanoelectronics as well as optoelectronics. We employ Djoković–Winkler relation to characterize the molecular topological networks of the coro-graphene nanosheets through distance-based descriptors. The work presents generalized expressions for distance-based topologies such as Szeged, Padmakar-Ivan, and Mostar types descriptors of coro-graphene nanosheets along with their novel weighted variants. We demonstrate through scaled natural logarithmic topological parameters that the network metamorphosis, irregularity and peripherealities can be characterized which can provide novel insights into reactivities and morphological changes as a function of the topologies of coro-graphenes.

Keywords: Coro-graphene nanosheets; Djoković–Winkler relation; Distance-based descriptors; Topological peripheralities; Network topologies
