Abstract

The present research project has as main goal the use of Computational Quantum Chemistry methods to characterize the electronic structure of electronic states and the polyhedral character of polycyclic aromatic hydrocarbon structures (PAHs) representative of graphene models. As specific objectives, we can divide the research lines to be developed in the following topics: a) study of electronic states and radical character of polyacenes; b) study of electronic states and radical character of periacenos; and c) study of permeability and induced selectivity by electronic excitation on graphene models porous membrane.
