Abstract

A supramolecular benzoylpyridinium-substituted cyclohexanediamine gelator with n-type redox properties was synthesized. The gelator formed a robust supramolecular network consisting of cyclohexanediamine units. In the organogel, the stable redox reactions of the benzoylpyridinium moieties led to a reversible charge/discharge at 1.05V (vs. Fc/Fc+). A supramolecule- based rechargeable device was fabricated using TEMPO- and benzoylpyridinium-substituted gelators as the cathode and anode, respectively, giving rise to a flexible, transparent, and even self-healable battery.
