Stretchable Polymer Semiconductors
Abstract
Flexible organic electronics (e.g. solar cells, light-emitting diodes and field-effect transistors) have attracted considerable attention over the past decade. Despite recent progress in developing new organic semiconductors, stretchable semiconducting or conducting elastomers have yet been explored in detail. Realization of these materials will result in increased robustness and potentially new applications in wearable electronics, since these materials can be fully solution processed and provide improved form factor (e.g. arbitrary 3D shapes) for organic devices. Therefore, the goal for this project is to develop materials chemistry and formulate an understanding to enable intrinsically stretchable electronic devices. Here, we propose two main molecular design concepts: (A) In the first concept, we propose to investigate the effects of H-bonding strength and regularity in bonding on the mechanical properties of semiconducting conjugated polymers. These studies will collectively provide important insights for rational design of stretchable organic semiconductors. (B) In the second molecular design concept, we will investigate a versatile approach for molecular design of intrinsically stretchable polymer semiconductors. We will investigate the use of molecular crosslinkers for improving ductility of semiconducting polymers. This work will provide us additional insights on molecular design for stretchable polymer semiconductors.
