Transformation of a copper complex to a 1-D coordination polymer to 3-D metal-organic frameworks

A new copper complex and two new copper coordination polymers were synthesized and transformed into metal-organic frameworks (MOFs). The copper polymer, Cu[(4 – 3-pbz)2(H2O)] ( 1 ), coordinates copper and  4-(3-pyridyl) benzoate and water molecules. The copper complex, Cu2[(4 – 2-pbz)4(DMF)2] ( 2 ), which forms a paddlewheel copper dimer coordinated with 4-(2-pyridyl)benzoate  and DMF molecules, was used to form a secondary copper polymer, Cu2[(bpy)(Acetate)4] ּ THF ( 3 ). The paddlewheel dimer motif was retained and was used as a metalloligand. It was reacted with the linkers, terephthalic acid (BDC) and 4-biphenyl dicarboxylic acid (BPDC), individually, to synthesize two MOFs.
