A robust two-dimensional zirconium-based luminescent coordination polymer built on a V-shaped dicarboxylate ligand for vapor phase sensing of volatile organic compounds

Abstract

We report herein a new two-dimensional zirconium-based luminescent coordination polymer Zr₆(sdba)₄(μ₃-O)₄(μ₃-OH)₄(HCOO)₂(OH)₂(H₂O)₂ (1) [sdba = 4,4′-sulfonyldibenzoate] exhibiting selective fluorescence responses towards a variety of volatile organic compounds upon exposure in the vapor phase. Having a unique two-dimensional signal response towards aromatic molecules, including but not limited to nitroaromatic explosives, it is capable of identifying a diverse set of analytes. In addition, compound 1 shows its remarkably high sensitivity toward acetone vapors.
