Covalent organic frameworks for electrochemical transistor

Research Project, 2024 – 2027

The direct communication between humans and electronics is one of the major targets for the current IT technology. To achieve this, a special medium is needed to connect electronic and biological systems. Organic electrochemical transistors (OECTs) are such devices that can transduce ionic signal to electronic signal, thus building a communication pathway between life and computers. The efficiency of an OECT device is heavily dependent on the transporting materials that are responsible for ionic and electronic conductance. However, the conventional OECT transporting materials are incapable of both large ionic capacitance and high electronic mobility, limiting OECTs' performance. To solve this problem, an emerging material, covalent organic framework (COF) will be inctroduced as a new generation of porous semiconductors for OECTs.
