Photoinduced Postsynthetic Polymerizatio no fa Metal-Organic Framework toward aF lexible Stand-Alone Membrane**

TLDR: In this paper, a post-synthetic polymerization (PSP) strategy was employed to covalently link MOF crystals by flexible polymer chains, endowing the MOF powders with processability and flexibility.

Abstract: Metal-organic frameworks (MOFs) are ap romising class of nanoporous polymeric materials .H owever ,t he proc- essing of such fragile crystalline powders into desired shapes for further applications is often difficult. Ap hotoinduced postsynthetic polymerization (PSP) strategy was now employed to covalently link MOF crystals by flexible polymer chains ,t hus endowing the MOF powders with processability and flexibility .N anosize dU iO-66-NH2 was first functionalized with polymerizable functional groups ,a nd its subsequent copolymerization with monomers was easily induced by UV light under solvent-free and mild conditions .B ecause of the improved interaction between MOF particles and polymer chains ,t he resulting stand-alone and elastic MOF-based PSP- derived membranes possess crack-free and uniform structures and outstanding separation capabilities for Cr VI ions from water. Metal-organic frameworks (MOFs) are nanoporous poly- meric materials constructed from metal ions or clusters that are covalently linked by organic ligands and thus possess the characteristics of both organic and inorganic materials.
