The electronic and optical properties of all molecules were investigated using the time dependent density functional theory (TD-DFT) and Gaussian 09 package [8] was employed throughout this calculation. The Slater-exchange [9] with VWN [10] correlation functionals for the local spin density approximation (LSDA), BLYP for the generalized gradient approximation (GGA), and hybrid B3LYP functional [11] were selected for describing the exchange-correlation functional terms. The LSDA functional depends only on the electron density: GGA functional depends on the density as well as the gradient of the electron density and hybrid functional mix SVWN and exact exchange with gradient correlation to exchange. Three different basis sets including the polarized (6-31G*), further expanded (6-311G**), and augmented Dunning’s correlation- consistent double-ξ basis (aug-cc-pVDZ) were selected to calculate the electronic structure of such these molecules. Finally, the B3LYP/aug-cc-pVDZ method has been chosen to calculate the electron affinity and ionization potentials because it can properly describe for the delocalized nature surface behavior of the lowest unoccupied orbital of such molecules. Optical properties of all molecules are calculated using the same basis set and method which its accuracy is sufficient for these calculations.
