Abstract

{Polymeric ionic liquids (i.e., PILs) are single ion-conducting materials that exhibit the thermal and electrochemical stability of ionic liquids and the mechanical properties of polymers. Although PILs are exciting for a variety of applications in energy conversion and storage, the tradeoff between mechanics and ion transport remains an important limitation in materials design. Herein, a photocrosslinkable PIL based on the cycloaddition reaction of anthracene is converted from a viscous liquid into a soft solid without detrimental effects on the bulk ionic conductivity. The independent control of mechanical- and ion-conducting properties results from negligible changes in polymer segmental dynamics (i.e., glass transition temperature) upon crosslinking. This was demonstrated for both a polymer (i.e.
