The densely fluorinated nanospace of a porous coordination polymer composed of perfluorobutyl-functionalized ligands

A perfluorobutyl-functionalized two-dimensional porous coordination polymer (PCP), {[Cu(bpbtp)(L)(DMF)]center dot(DMF)}(n) (H(2)bpbtp = 2,5-bis(perfluorobutyl) terephthalic acid, L = 2,5-bis(perfluorobutyl)-1,4-bis(4-pyridyl)benzene, DMF = N, N-dimethylformamide) has been synthesized and structurally characterized. The pore surface of the PCP is decorated with pendant perfluorobutyl groups which fabricate a densely fluorinated nanospace resulting in unique gas sorption properties.
