AB  - <jats:title>Abstract</jats:title><jats:p>Ntype conjugated polymers as the semiconducting component of organic electrochemical transistors (OECTs) are still undeveloped with respect to their ptype counterparts. Herein, we report two rigid ntype conjugated polymers bearing oligo(ethylene glycol) (OEG) side chains, PgNaN and PgNgN, which demonstrated an essentially torsionfree πconjugated backbone. The planarity and electrondeficient rigid structures enable the resulting polymers to achieve high electron mobility in an OECT device of up to the 10<jats:sup>−3</jats:sup>cm<jats:sup>2</jats:sup> V<jats:sup>−1</jats:sup> s<jats:sup>−1</jats:sup> range, with a deeplying LUMO energy level lower than −4.0eV. Prominently, the polymers exhibited a high device performance with a maximum dimensionally normalized transconductance of 0.212S cm<jats:sup>−1</jats:sup> and the product of chargecarrier mobility <jats:italic>μ</jats:italic> and volumetric capacitance C of 0.662±0.113F cm<jats:sup>−1</jats:sup> V<jats:sup>−1</jats:sup> s<jats:sup>−1</jats:sup>, which are among the highest in ntype conjugated polymers reported to date. Moreover, the polymers are synthesized via a metalfree aldolcondensation polymerization, which is beneficial to their application in bioelectronics.</jats:p>
