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

摘要

A microporous MOF [Zn_4(OH)_2(1,2,4-BTC)_2] (1,2,4-BTC = Benzene-1,2,4-tricar boxy late) with two immobilized open metal Zn~(2+) sites was obtained by solvothermal reaction, which exhibits highly selective guest sorption and sensing of nitrobenzene.rnMicroporous metal-organic frameworks (MOFs) have been rapidly emerging as a new type of porous materials for gas storage, separation, sensing and heterogeneous catalysis. The tunable pores and the immobilized functional sites within such microporous MOFs have enabled them to direct specific recognition of certain molecules, and thus for their highly selective guest sorption and separation.
