We are investigating the microstructure of structural defects in crystalline organic semiconductors. These materials are of current interest for flexible flat panel displays, radio-frequency ID tags, photovoltaics, and biosensors. Our work has focused on the high resolution imaging of vacancies, dislocations, and grain boundaries. We are currently examining variants of pentacene that contain side groups designed to promote solubility in common organic solvents and face-to-face interactions between the flat molecules when packed into crystals. We are also investigating systems with the ability to form liquid crystalline mesophases. |
