Over Tenfold Increase in Current Amplification Due to Anisotropic Polymer Chain Alignment in Organic Electrochemical Transistors.

ABSTRACT: Organic electrochemical transistors (OECTs) are central to the development of highly sensitive (bio)sensors, energy-efficient neuromorphic devices, and high-precision electrophysiological monitoring systems. With growing interest in these strategic electronic devices, a novel PBTTT polymer bearing single-ether side chains (PBTTT-⁸O) in OECTs is investigated. Pristine isotropic non-aligned OECT performance matches state-of-the-art transconductance, highlighting the potential of single ethers for designing high-performance organic mixed ionic-electronic conductors (OMIECs). Moreover, a 13× enhancement of current output is achieved by anisotropic polymer chain alignment of PBTTT-⁸O, opening doors to unprecedented device sensitivity. Compared to pristine ones, aligned OEC
