Isotropic proton conduction in an anisotropic crystal: the role of molecular rotational dynamics in imidazolium dihydrogen phosphate
Shun Dekura, Motohiro Mizuno, Hatsumi Mori
Abstract
anions, effectively connects the proton conduction pathways, resulting in isotropic conductivity despite the anisotropic hydrogen-bond network. These findings demonstrate that the cooperative rotational dynamics of both acid and base components is a valid strategy for designing high-performance anhydrous proton-conducting materials.
