Abstract
Broadly, this thesis work focused on the investigation and leveraging of the way in which conjugated polymers shuttle and interact with electrons/ions. This mixed ion and electron transport has led to their use in a wide range of semiconductor applications, including bio(electronics). Commercialization of these materials for such applications will be difficult without high-throughput industrial processing techniques such as roll-to-roll and additive manufacturing. Accordingly, this thesis focuses on the design, synthesis, and characterization of CPs with solution processability — a key requirement for such manufacturing technologies — to outline specific structure-property relationships that expand their viability for applications in varying design spaces (films, filaments, multi-layer architectures, etc.). For application-driven work, organic electrochemical transistors (OECTs) have been of significant contemporary interest due to their mechanical conformability, low-voltage operation, facile chemical modification, and ability to transduce cellular ion fluxes (e.g., protons, metal ions, and neurotransmitters) into exogeneous electrical signals with extremely high signal fidelity. Accordingly, this work further aimed to understand the interplay between polymer (polythiophene-based active material) chemical structure, processing, and material properties relevant to enhancing OECT performance and stability.
