Abstract
The organic electrochemical transistor (OECT), capable of transducing small ionic fluxes into electronic signals in an
aqueous environment, is an ideal device to utilize in bioelectronic applications. Currently, most OECTs are fabricated with commercially
available conducting poly(3,4-ethylenedioxythiophene) (PEDOT)-based suspensions and are therefore operated in depletion
mode. Here, we present a series of semiconducting polymers designed to elucidate important structure-property guidelines required
for accumulation mode OECT operation. We discuss key aspects relating to OECT performance such as ion and hole transport,
electrochromic properties, operational voltage and stability. The demonstration of our molecular design strategy is the fabrication of
accumulation mode OECTs that clearly outperform state-of-the-art PEDOT based devices, and show stability under aqueous operation
without the need for formulation additives and cross-linkers.
