A Model for Calculate Some Electro- Optical Properties of Acenes Using Wiener Index

A topological representation of a molecule can be carried out through molecular graph. The descriptors are numerical values associated with chemical constitution for correlation of chemical structure with various physical properties, chemical reactivity or biological activity. A topological index is the graph invariant number calculated from a graph representing a molecule. In this study Wiener index in family acenes were calculated with some electronic and optical properties desired for a number of elements of the family, a model for predicting the electronic and optical properties by Wiener index has introduced. To offer this model, the electronic and optical properties of acenes were calculated using mathematical software, and the results compared by the data sources.
