1D porous Zinc(II) Coordination Polymer as Fluorescent Chemosensors for Nitrobenzene and Fe3+

Abstract

This paper studies the luminescence-sensing properties of 1D porous zinc coordination polymer [Zn(3-tba)₂]·DMA (1, 3-Htba = 3-(4H-1,2,4-triazol-4-yl)benzoic acid, DMA = N,N-dimethylacetamide). The systematic luminescence experiments indicate that it can be potentially used as a fast-response fluorescence sensor for the sensitive detection of nitrobenzene and Fe³⁺ ion through drastic fluorescence quenching. Moreover, the quenching mechanisms of 1 towards nitrobenzene and Fe³⁺ were also investigated.
