Mechanistic synthesis of a sequential calcium-carboxylate-based linker (Ca-MOFs) and rapid assessment of chemical stability through XRD analysis

Many MOFs based on various metal ions including s-, p-, d-, and f-block elements have been developed over the past decade. Despite their abundance, low cost, and non-toxicity, s-block MOFs have been explored less frequently than those based on transition metals and f-block metal ions. Sequential cal...
