摘    要:Two novel zinc(Ⅱ) coordination polymers, Zn_2(BCB)(CH_3OH)(μ_3-OH)]n(1) and {Zn_2(BCB)(μ_3-OH)(H_2O)_2]·CH_3OH}n (2), have been constructed from 3,5-bis(2-carboxylphenoxy)benzoic acid(H_3BCB) and characterized by elemental analysis(EA), IR, powder X-ray diffraction(PXRD), and thermogravimetric(TG) analyses. Structural analysis reveals that complexes 1 and 2 are both 1D polymeric chains with unprecedented tetranuclear {Zn_4(COO)_4(μ_3-OH)_2} clusters, which were further expanded into a 2D structure. Fluorescence measurements show that 1 and 2 have highly selective and sensitive detection of nitrobenzene.
