We prepared a series of ionic complexes, [CnMim][CHP] (n = 6–18), by neutralizing cholesterol hydrogen phthalate (CHP) with 1-alkyl (Cn)-3-methylimidazolium hydroxide ([CnMim][OH]) derived from [CnMim][Br]. The complexes of n ≥ 10 formed a thermotropic mesophase in each individual temperature range and solidified into a mesomorphic glass upon cooling, although two samples of n = 6 and 8 showed no ordered structure. Enthalpy relaxation behavior of the mesomorphic glasses (n = 10, 18) was also examined as a function of the aging temperature and time
