Self-Doped Mixed Ionic-Electronic Conductors to Tune the Threshold Voltage and the Mode of Operation in Organic Electrochemical Transistors

Organic mixed ionic-electronic conductors with tunable doping, low threshold voltages, and air stability are crucial for bioelectronic applications. A homopolymer based on an alkoxy thiophene monomer and its copolymer with a thiophene carrying ethylene glycol side chains are synthesized and converted to self-doped conjugated polyelectrolytes, P3HOTS–TMA+, and P3HOTS–TMA+-co-P3MEEET. The self-doping occurs during the conversion to […]
