The performances of Density Functional Theory (DFT) and Time Dependent DFT (TD-DFT) in the prediction of ground and excited state properties of molecular systems (both fully organic or containing d transition metals) will be reviewed by selected examples of compounds used in molecular devices with application ranging from hybrid photovoltaic cells to molecular devices [1-3].
Special emphasis will be devoted to the possibility of providing a realistic description of the environmental effects (ex. solvent, absorption on a surface, encapsulation, molecular crystals) on the overall photophysical properties of these systems by the means of theoretical methods ranging from continuum polarisable models for solvent, cluster approaches, QM/QM' to fully periodic calculations [4-5].
Finally, the possibility of using density based descriptors [6-7] both to quantify the extent and magnitude of transferred charge associated to a charge transfer (CT) excitation [8-10] and to describe excited state reactions and interconversions [11-14] will be illustrated.
