摘要
Two novel zinc（Ⅱ） coordination polymers, [Zn2（BCB）（CH3OH）（μ3-OH）]n（1） and {[Zn2（BCB）（μ3-OH）（H2O）2]·CH3OH}n （2）, have been constructed from 3,5-bis（2-carboxylphenoxy）benzoic acid（H3BCB） 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 {Zn4（COO）4（μ3-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.
