Abstract

Four isostructural coordination polymer crystals having different metal ions were synthesized and studied for ball milling-induced glass formation. Distinct glass formation was discussed from crystal structures. Doping of molecules for CP glass during the milling was demonstrated, and it resulted in tunable glass properties (T_g and T_c) and enhancement of anhydrous H⁺ conductivity.
