Summary Low molecular weight gelators bearing 2,2,6,6‐tetramethyl‐piperidine‐1‐oxyl (TEMPO) were synthesized and demonstrated to have reversible electrochemical redox properties. The gelation tests showed that the compounds have excellent gelation properties in γ‐butyrolactone and propylene carbonate. Atomic force microscopy and transmission electron microscopy images showed the 3D network fibrous structure with an average diameter of 20–50 nm. Fast and reversible charge storage capabilities were established for the gelators, with an average output voltage of 4.8 V.
