Three microporous Zn coordination polymers constructed by 3,4,5-tris(carboxymethoxy)benzoic acid and 4,4′-bipyrdine: Structures, topologies, and luminescence

Multicarboxylate 3,4,5-Tris(carboxymethoxy)benzoic acid, together with rigid 4,4′-bpy and/or hydroxyl groups, join Zn2+ to obtain three different microporous Zn MOFs with helical structures based on polynuclear metal-hydroxyl clusters. Photoluminescent properties are also investigated.152
