Short Naphthalene Organophosphonate Linkers to Microporous Frameworks

摘要

We report two novel 3D porous metal-organophosphonate metal organic frameworks (MOFs) [{Cu(4, 4’-bpy)_(0.5)(1,4-NDPAH2)] (1), [{Cu2(4,4’-bpy)_(0.5)}(1,4-NDPA)] (2) and a non-porous [{Cu(4, 4’-bpy)}(2,6-NDPA-H2)] (3) constructed using the structurally rigid 1,4-naphthalenediphosphonic acid (1,4-NDPA-H4) and 2,6-naphthalenediphosphonic acid (2,6-NDPA-H4). 1 and 2 exhibit high surface areas obtained using the structurally rigid and short aromatic organophosphonate linkers with copper. The compound 1 has been further analyzed by TGA and Quantum Design PPMS vibrating sample magnetometer.
