A rod packing microporous metal–organic framework with open metal sites for selective guest sorption and sensing of nitrobenzene

A microporous MOF [Zn4(OH)2(1,2,4-BTC)2] (1,2,4-BTC = Benzene-1,2,4-tricarboxylate) with two immobilized open metal Zn2+ sites was obtained by solvothermal reaction, which exhibits highly selective guest sorption and sensing of nitrobenzene.
