Abstract

Topological indices collect information from the graph of molecule and help to predict properties of the underlying molecule. Zagreb indices are among the most studied topological indices due to their applications in chemistry. In this paper, we compute first and second reverse Zagreb indices, reverse hyper-Zagreb indices and their polynomials of Prophyrin, Propyl ether imine, Zinc Porphyrin and Poly (ethylene amido amine) dendrimers.

Summary

Introduction

Dendrimers, from a Greek word that translates to “trees” [1,2], are repetitively branched molecules. Dendrimers are generally symmetrical about the core and generally adopt a spherical three-dimensional morphology. Dendrites usually contain a single chemically addressable group called the focus or core. The first dendrimer was made by Fritz. Vogtle [3] using different synthetic methods, such as by RG Denkewalter at Allied [4,5] and Donald. Tomalia at Dow Chemical [6,7,8]. Craig Hawker and Jean Frechet in 1990 [9]
