Abstract

A dendrimer is an artificially manufactured or synthesized molecule built up from the branched units called monomers. Dendrimers are among the most intricate chemical and fascinating structures and hyper-stretched macromolecules, with a correctly custom fitted engineering. Dendrimers have increased a wide scope of use in supra-molecular chemistry, especially in host-guest reactions and the self-assembly process. Their applications in biology, chemistry, science and nano-science are boundless.

Quantitative structure-property and structure-activity relationships of the dendrimer compounds necessitate expressions for the molecular topological features of these compounds. Topological descriptors are the significant numerical quantities in the fields of chemical graph theory. Ev-degree and ve-degree based topological indices are two novel degrees based indices as of late defined in graph theory. Ev-degree and ve-degree based topological indices have been defined as corresponding to their relating partners. In this paper, we have computed topological indices based on ev-degree and ve-degree for the two families of Polycyclic Aromatic Nanostars Dendrimers compounds.

摘要

树枝状大分子是人工制造或合成的分子，由称为单体的支链单元构成。树枝状大分子是最复杂的化学和迷人结构以及超拉伸大分子之一，具有正确定制的工程。树枝状大分子在超分子化学中的应用范围越来越广，特别是在主客体反应和自组装过程中。它们在生物学、化学、科学和纳米科学中的应用是无限的。

树枝状大分子化合物的定量结构-性质和结构-活性关系需要表达这些化合物的分子拓扑特征。拓扑描述符是化学图论领域中重要的数值量。基于 Ev 度和 ve 度的拓扑索引是最近在图论中定义的两个新的基于度的索引。基于 Ev 度和 ve 度的拓扑指数已被定义为对应于它们的相关伙伴。在本文中，我们计算了基于 ev 度和 ve 度的两个多环芳族纳米星树枝状化合物家族的拓扑指数。
