Creating glassy states of dicarboxylate-bridged coordination polymers

We report the direct formation of dicarboxylate-based coordination polymer glasses through thermal dehydration. The rearrangement of the coordination networks caused by dehydration was monitored by in situ powder X-ray diffraction, infrared spectroscopy, and synchrotron X-ray characterizations. The microporosity and mechanical properties of these glasses were investigated. A series of dicarboxylate-bridged networked glasses with tunable porosity and mechanical properties were obtained by dehydration of hydrated coordination polymer crystals.
