Some Electronic and Optical Properties of Nanostructures Using the First Zagreb Index

Topological index of a molecular graph is a number that is attributed to molecular graph. This number can express some of the properties of molecules. In this article, the first Zagreb index was calculated in the family phenacenes and a suitable model was provided to predict the electronic and optical properties through first Zagreb index while considering some of the electronic and optical properties of a number of optional elements of this family. In order to propose this model, the electronic and optical properties of phenacenes were calculated by the computing software and then compared with the data in valid references.
