Polymer Sequence Design of Zwitterionic Polymer/PEDOT:PSS Blend Films for Improved Charge Transport and Stability in Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
Solution blending of zwitterionic polymers with PEDOT:PSS provides a simple route to OECT materials with enhanced threshold voltage stability in biologically relevant environments. The polymer sequence alters outer‐domain structure within the preserved PEDOT:PSS framework, thereby tuning charge transport.

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

Advanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.
