Structure-property engineering and device fabrication of conjugated polymers by chemical vapor deposition

This thesis focuses on the in-situ molecular engineering of chemical vapor deposition (CVD)-synthesized soft materials and device applications. High quality and large-scale synthesis of soft materials are the foundation of soft electronics. CVD approach has proved to be a low-cost and scalable technique to synthesize a wide variety of soft materials with desired properties. The first part (Chapter 2) will be dedicated to the record high electrical conductivity in CVD-grown poly(3,4-ethylenedioxythiophene) (PEDOT) thin films with controllable crystallization and morphology. The polymeric conducting thin film can be used as flexible and transparent electrodes in many electronic devices. Previously, the key problem limiting the electrical conductivity of PEDOT is the difficulty of maintaining a high carrier mobility simultaneously with a high carrier density in this polymer.
