Organic Materials - Understanding physical processes

Organic materials that are based on carbon chemistry and that can assemble into supramolecular structures using additional non-covalent bonding mechanisms have a great level of structural flexibility. This property can be used to tailor the properties of a material for a given application and is, therefore, an advantage. However, it is simultaneously a disadvantage because the possibilities to modify a given molecule are nearly infinite.

Furthermore, most of the fundamental physical processes such as charge injection, charge transport, photodissociation of excitons, or recombination are not as well understood as in inorganic crystalline materials.

Another challenge is that the structure of organic materials in the solid state can be more complex than that of inorganic semiconductors such as silicon and diffiult to predict and control.

Therefore, breakthroughs in organic nanotechnologies require a continuous better understanding of the chemistry, physics and material science of the new materials under development. These advances are guided by the development of structure-property relationships and require the integration of experimental studies with theoretical modeling.

Our research group has active collaborations with the group of Prof. Jean-Luc Bredas at Georgia Tech in this area.
