基于分子图顶点(原子)距离的拓扑指数被广泛用于表征分子图及其碎片,建立分子的结构和性质之间的关系,预测化合物的生物活性,以及其他化学应用。多苯是一类重要的大环芳烃及其衍生物,可用于有机合成、药物合成、热交换器等领域。本文研究了树状多苯体系中Wiener指数与其它距离拓扑指数的关系,得到了它们之间的精确关系式。
Topological indices based on the distances between vertices(atoms) of a molecular graph are widely used for characterizing molecular graphs and their fragments, establishing relationships between structures and properties of molecules, predicting biological activity of chemical compounds, and making other chemical applications. Polyphenyls are a kind of macrocyclic aromatic hydrocarbons and their derivatives are very important organic chemicals, which can be used in organic synthesis, drug synthesis, heat exchanger, etc. In this paper we investigate the relationships between the Wiener index and other distance-based topological indices in the tree-like polyphenyl systems and obtain some exactly formulae on the relationships.
