摘要

We demonstrate switching of ionic conductivities in wedge-shaped liquid-crystalline (LC) ammonium salts. A thermoreversible phase transition between the rectangular columnar (Col_r) and hexagonal columnar (Col_h) phases is used for the switch. The ionic conductivities in the Col_h phase are about four orders of magnitude higher than those in the Col_r phase. The switching behavior of conductivity can be ascribed to the structural change of assembled ionic channels. X-ray experiments reveal a highly ordered packing of the ions in the Col_r phase, which prevents the ion transport.
