Abstract:

Printed, flexible electronics have the potential to be produced at sufficiently low cost to enable ubiquitous electronic control and monitoring in health care, environmental quality, national security, and systems integrity. We developed fundamental understanding of materials and devices using a systematic approach to identify how structure and processing impact morphology, interfaces, and devices. We investigated how rigid rod-conjugated systems interact and in solution and during the film formation process. These interactions are the antecedent to the - stacked networks that are crucial for charge transport. In situ spectroscopic experiments identified specific molecular interactions and processes required for the development of effective -conjugated systems that allow efficient intra- and intermolecular charge transport. Knowledge concerning how these systems associate to form effective -conjugated networks informs the design and development of materials and processes for viable, robust, flexible electronics.
