A new multi-functional metal-organic framework, {[Cu2(HL)(H2O)2]·NMP·2H2O}n (1), was assembled employing a asymmetrical V-shaped rigid multicarboxylic acid ligand H5L (H5L= 2,4-di(2′,5′-dicarboxylphenyl)benzoic acid) with Cu(II) ions. 1 possesses a 3D pore formed...
In situ near edge X-ray absorption fine structure spectroscopy directly probes unoccupied states associated with backbonding interactions between the open metal site in a metal–organic framework and various small molecule guests.
