Theoretical insight into the electronic, optical, and structural properties of π-conjugated molecular, oligomer, and polymer materials.
Description of the key physico-chemical processes taking place in π-conjugated materials and guidance for the development of new compounds with improved characteristics:
interpretation of the doping mechanism in conjugated polymers leading to high electrical conductivity; demonstration of the specific ways in which excess charges are stored on the polymer chains in the form of nonlinear excitations such as solitons, polarons, and bipolarons;
design of conjugated polymers with very small intrinsic band gaps;
unified description of linear and nonlinear optical response of organic chromophores;
characterization of the interfaces formed between metal or conducting oxide electrodes and organic layers;
elucidation of the structure - charge transport relationships in organic semiconductors; illustration of the impact of chemical structure and molecular packing on the reorganization energies and electronic couplings between adjacent molecules/chains;
integrated theoretical approach to the description of the electronic and optical processes taking place in organic solar cells.
band-structure engineering in two-dimensional π-conjugated polymer networks (or COFs, covalent organic frameworks).
