Several distance and degree-based molecular structural attributes of cove-edged graphene nanoribbons. | LitMetric

AI Article Synopsis

  • Graphene is a carbon-based material known for its beneficial properties, and recent developments include a novel cove-edged graphene nanoribbon created using a bottom-up liquid-phase method.
  • This nanoribbon features asymmetrical edges formed by hexagonal patterns, combining characteristics of both armchair and zigzag edges, providing exceptional mechanical and electrical properties.
  • The article introduces topological indices, which are mathematical values derived from molecular structures, to accurately describe the cove-edged graphene nanoribbons, potentially streamlining laboratory research on their properties.

Article Abstract

A carbon-based material with a broad scope of favourable developments is called graphene. Recently, a graphene nanoribbon with cove-edged was integrated by utilizing a bottom-up liquid-phase procedure, and it can be geometrically viewed as a hybrid of the armchair and the zigzag edges. It is indeed a type of nanoribbon containing asymmetric edges made up of sequential hexagons with impressive mechanical and electrical characteristics. Topological indices are numerical values associated with the structure of a chemical graph and are used to predict various physical, chemical, and biological properties of molecules. They are derived from the graph representation of molecules, where atoms are represented as vertices and bonds as edges. In this article, we derived the exact topological expressions of cove-edged graphene nanoribbons based on the graph-theoretical structural measures that help reduce the number of repetitive laboratory tasks necessary for studying the physicochemical characteristics of graphene nanoribbons with curved edges.
