We studied low-molecular-weight gelators which are capable of gelling up ionic liquids. From the results of gelation test, we found that cyclo(dipeptide)s, which are prepared from artificial sweetener Aspartame, are good gelators for ionic liquids. The formed gels showed thermally reversible sol-t0-gel transition due to the non-covalent interactions. Gels of ionic liquids were characterized by high ionic conductivity. For instance, the ionic conductivity of C4mim/BF4 gel was 3.20 mS/cm. This result indicates that the gelator molecules hardly interfere with the mobility of anion and cation.
