Formation of coordination polymer glass by mechanical milling: dependence on metal ions and molecular doping for H+ conductivity.

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 (Tg and Tc) and enhancement of anhydrous H+ conductivity.
