Organic Reprogrammable Circuits Based on Electrochemically-Formed Diodes

• To simplify the integration of organic electronics, we demonstrate a method for constructing reprogrammable circuits based on organic diodes. The organic p‐n junction diodes consisting of an organic polymers poly[2‐methoxy‐5‐(2‐ethylhexyloxy)‐1,4‐phenylenevinylene and an electrolyte were formed by electrochemical doping at 70 °C, and stabilized at ‐30 °C. The reversible electrochemical reaction allows for the in‐situ change of the polarity of the organic p‐n junction. By forming diodes with different polarity at different locations, several circuits can be created, such as, logic gates, voltage limiter and AC/DC converter. The as‐made circuitry can be erased and turned into circuitry with other functionality. For example, the diodes of an AND gate can be re‐programmed to form an OR gate. The reprogrammable circuits contain merely two core layers, electrodes and active material, which is promising for large‐area and fully‐printed reconfigurable circuits with facile fabrication.
