A new tetrathiafulvalene (TTF) derivative with two cholesterol units (compound 1 ) was synthesized and characterized. Gelation of n ‐hexane occurred after the hot solution of 1 was subjected to ultrasonic treatment for a few minutes. The resulting organogel was characterized with SEM, XRD and AFM. Besides heating the gel‐sol transition also occurred upon addition of I 2 which can oxidize the TTF unit in 1 . This result provides a new example of organogels responding to redox reactions. Interestingly, gelation‐induced CD signals were observed and the CD signals can be tuned with the gel‐sol transition which can be effected by heating and chemical reaction with I 2 .
