A 3D heterometallic metal–organic framework constructed from luminescent building blocks, exhibiting reversible dehydration and rehydration procedure

A novel metal–organic framework constructed from luminescent building block, [Tb(pydc)3]3−, and alkaline earth ion has been designed and synthesized. It illustrates a three-dimensional (3D) structure with nano-channels, and shows reversible dehydration and rehydration behavior.
