Selective fluorescence sensing properties of a novel two-fold interpenetrating coordination polymer

Abstract

A new Zn(II) coordination polymer, namely, {[Zn₂(BIP)₂(L)]·2H₂O}_n (1) (H₄L = 5,5′-(triazole-2,5-diyl)diisophthalic acid, BIP = 4,4′-bis(imidazol-1-yl)phenyl) has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction, IR spectroscopic, elemental and thermogravimetric analyses. Single-crystal X-ray diffraction analyses indicate that CP 1 exhibits a unique 3D two-fold interpenetrated network with a point symbol of {6⁴·8²}. CP 1 displays high sensitivity in the detection of acetone, Fe³⁺, Cu²⁺, Cr₂O₇²⁻, CrO₄²⁻ and nitrofurantoin (NFT) in N,N-dimethylformamide (DMF).
