摘要：

A Zn-based coordination polymer [zn(oba)(2)(bpy)(2)] (1) (where oba = 4,4' -oxybisbenzoic acid, bpy 4,4'-bipyridine) has been synthesized under solvothermal condition and characterized by single-crystal X-ray diffraction. Thermal and water stability research revealed that it has good thermal and hydrolytic stability. Most stirringly, the luminescence investigation demonstrated that 1 can exploit as a highly selective and sensitive multi-responsive luminescence sensor for detecting Fe3+ cation and Cr2O72-/CrO42- anions in aqueous solutions through luminescence quenching effects, even in the presence of other interfering ions. In connection to these, the probable sensing mechanisms were also discussed.
