Abstract
Provided here are ion conducting materials including one or more macrocycles, and either one or more pendant groups or one or more backbone repeat units. The ion conducting materials exhibit distinctly high ion conductivity in thin film and bulk membrane applications, and further exhibit one or more of ion permselectivity, mechanical strength, self-assembly, stacking, and gating behavior. Further provided are methods for preparation and methods for use of the ion conducting materials.
Claims20
An ion conducting material comprising:
- one or more macrocyclic repeat units, the macrocyclic repeat units comprising a macrocycle which is a calix[n]arene where n is an integer from about 4 to about 20, a crown ether, a cyclodextrin, or a porphyrin;
- a pendant group;
- and/or
- optionally one or more backbone repeat units,
- wherein the pendant group and the one or more backbone repeat units are chemically bonded to the macrocycle to form an ion conduction pathway of the ion conducting material, and wherein the pendant group, the one or more backbone repeat units, or both, comprise an ion conducting functional group to enable movement of ions through the ion conduction pathway of the ion conducting material.
