Donor-Acceptor group effects on structure and NLO properties of some small Fullerenes

In this study the influence of donor and acceptor groups on structures, electrical and optical properties of some small fullerene, C20, C24 and C26, were explored. It was displayed that the donor and acceptor groups presence have drastic effects on their structures. Additionally it was demonstrated that the electrical properties of those fullerenes were considerably influenced by the donor and acceptors groups’ existence. In final part it is illustrated that the linear and non-linear optical properties of these nanoclusters is remarkably enhanced in presence of the donor and acceptor groups.
