Elucidation of conduction mechanism and developments of materials design guidelines of anhydrous super-proton conducting molecular solids

We are engaged in material exploration and multifaceted physical property evaluations, as well as conductivity mechanism studies, to establish design principles for molecular solids that can rapidly conduct hydrogen ions (protons: H+) as intrinsic material properties without requiring the introduction of water molecules through humidification. As a result, we have discovered multiple anhydrous superprotonic conductors by leveraging molecular motion in solids and have successfully proposed and demonstrated "proton tautomerism" as a novel conduction mechanism that does not rely on molecular motion.
