The use of self-assembly of ionic liquid-crystalline molecules is a powerful approach to the formation of ion transport nanochannels. We herein present a series of anhydrous proton-conducting liquid crystals based on Brønsted acid-base pairs. Taper-shaped sulfonic acids are synthesized. Complexation of the sulfonic acids with imidazole stabilizes the liquid-crystalline phases and induces the drastic structural change. For example, the equimolar complex of the sulfonic acid tethering a
