Award-winning pulication: Ionic liquid–water mixtures and ion gels as electrolytes for organic electrochemical transistors

Published in: Journal of Materials Chemistry C, vol. 3, juin 2015, p. 6549


Ionic liquids (ILs, molten salts) have been recognized as extraordinary solvents, media and electrolytes for applications in chemistry, physics and biology. Nevertheless, ILs can exhibit excessively high viscosity that prevents their straightforward application in organic electrochemical transistors (OECT). Zhihui Yi's work has provided the understanding that the microstructure of the electrolyte might also play a role in the doping/dedoping process in OECTs to be applied in bioelectronics. Organic bioelectronics is a booming and still largely unexplored multidisciplinary field. An improved understanding of the working mechanism of IL-H2O binary mixtures and ion gel based OECTs, the electrolytes designed by Zhihui Yi, is expected to advance the state of the art of ionic liquid based organic bioelectronics.
