Abstract

Topological indices are mathematical descriptors of the structure of a molecule that can be used to predict its properties. They are derived from the graph theory, which describes the topology of a molecule and its connectivity. The main objective is mathematical modeling and topological properties of ϒ-graphyne. Current research focuses on two structures made from hexagonal honeycomb graphite lattices named triangular ϒ-graphyne and triangular ϒ-graphyne chains. The authors have simultaneously computed the first and second Reverse Zagreb indices, reverse hyper-Zagreb indices, and their polynomials. This research also derives mathematical closed-form formulas for some of its fundamental degree-based molecular descriptors. Researchers have been trying to synthesize a novel carbon form called Graphyne. For over a decade but with no success. Recently, some researchers have made a breakthrough in generating Carbons elusive allotrope and solved a long-standing problem in carbon materials. This wonder material is created to rival the conductivity of graphene but with control. These results opened new ways of research in the fields of semiconductors, electronics and optics. Furthermore, graphical and tabular results will help to investigate the structure-property relationships in γ-graphyne.
基于拓扑指数的三角ϒ-石墨烯和三角ϒ-石墨烯链分子结构反向研究
拓扑指数是分子结构的数学描述符,可用来预测分子的性质。拓扑指数源于图论,图论描述了分子的拓扑结构及其连通性。主要目标是建立ϒ-graphyne 的数学模型和拓扑特性。目前的研究重点是由六边形蜂窝石墨晶格制成的两种结构,分别命名为三角形ϒ-石墨烯和三角形ϒ-石墨烯链。作者同时计算了第一和第二反向萨格勒布指数、反向超萨格勒布指数及其多项式。这项研究还推导出了一些基于基本度的分子描述符的数学闭式公式。研究人员一直在尝试合成一种名为石墨烯的新型碳。但十多年来一直没有成功。最近,一些研究人员在生成碳这种难以捉摸的同素异形体方面取得了突破性进展,解决了碳材料领域的一个长期难题。这种神奇的材料可以与石墨烯的导电性相媲美,但却可以控制。这些成果为半导体、电子学和光学领域的研究开辟了新途径。此外,图形和表格结果将有助于研究γ-石墨烯的结构-性能关系。
