Influence of an amine group on the highly efficient reversible adsorption of iodine in two novel isoreticular interpenetrated pillared-layer microporous metal-organic frameworks

摘要

Two isoreticular microporous Zn(II)-MOFs were constructed using a bipyridyl-type linker mixed into two homologous ligands, 1,4-benzenedicarboxylate, [Zn-2(BDC)(2)(4-bpdh)]center dot 3DMF (TMU-16) and amino-1,4-benzenedicarboxylate, [Zn-2(NH2-BDC)(2)(4-bpdh)]center dot 3DMF (TMU-16-NH2). Both unmodified and amino functionalized MOFs can serve as a host for encapsulating I-2. In particular, the amino functionalized MOF can find more applications for the encapsulation of iodine.
