Recent development on the alkaline earth MOFs (AEMOFs)

As one of the important subclasses of MOFs, Alkaline earth (group II) metal–organic frameworks (AEMOFs) in recent years also have caught much attention not only because of their fascinating structures but also because of their nontoxicity, relatively low densities, low cost and stability, etc. These merits make them have many potential applications in implementation and industrial fields. In this review, we will give a succinct description of the recent development on the AEMOFs (including the homometallic and heterometallic AEMOFs): some representative structures and physicochemical properties, such as proton conductivity, magnetism, gas or guest adsorption/separation, chromism, heterogeneous catalysis, biomedical applications, as well as luminescent sensing, are presented in this review. Fully understanding the structure–property relationship of the AEMOFs is still a long way, we hope this review could give some inspirations and help to chemists to explore the syntheses and applications of the AEMOFs in much more fields.
