Summary: Organic electrochemical transistors (OECTs) based on conjugated polymers have gained significant interest in flexible bioelectronics due to their high transconductance, low operating voltage, and good biocompatibility. The performance of OECTs is influenced by the mixed ionic and electronic transport properties of organic semiconductors, which in turn are determined by molecular packing and film morphology. While efforts have been made on new polymer structures, the relationship among chemical structure, molecular packing, film morphology, and OECT performance is still not fully explored.
