Abstract |
Porphyrins and fullerenes donor-acceptor complexes are covalently linked in all these structures and adopt specific conformations that allow the π-electron systems to interact, even in the ground state. This has been attributed to strong van der Waals interactions. We calculated the Expanded Porphyrins (host 1,2) and complex Expanded Porphyrins: Cn Fullerenes (n=60, 70, 76, 84) using density functional theory (DFT) with a 6-31G(d) basis set. In order to include the solvent polarization effect was used in calculation for the Expanded Porphyrins (host 1,2) and complex Expanded Porphyrins: Cn Fullerenes (n=60, 70, 76, 84) in toluene and benzonitrile. After optimization, the absorption and frontier molecular orbitals (FMOs) for Expanded Porphyrins (host 1,2) and complex Expanded Porphyrins: Cn Fullerenes (n=60, 70, 76, 84) were carried out with the time dependent-density functional theory (TD-DFT), method using TD-M062X/6-31G+(d) level of theory. |
