The Edge Versions of Degree-Based Topological Descriptors of Dendrimers

In the study of the quantitative structure–activity relationship and quantitative structure–property relationships, degree-based topological indices are the most prominent and can be used to characterize the chemical compounds and predict their certain physiochemical properties like molecular weight, boiling point, refractive index, density, etc. Dendrimers are highly branched, star-shaped macromolecules with nanometer-scale dimensions. Dendrimers are defined by three components: a central core, an interior dendritic structure (the branches), and an exterior surface with functional surface groups. In this paper, we compute closed formulae of edge versions of forgotten index, Hyper-Zagreb index, sum-connectivity index, harmonic index, augmented Zagreb index and Randic index for fluorescent water-soluble PDI-cored cationic dendrimers and trizane based dendrimers.
