Abstract

A novel Zn^II coordination polymer, namely, poly[{μ₂-bis[4-(2-methyl-1H-imidazol-1-yl)phenyl]methanone-κ²N³:N^3'}(μ₂-5-bromobenzene-1,3-dicarboxylato-κ²O¹:O³)zinc(II)], [Zn(C₈H₃BrO₄)(C₂₁H₁₈N₄O)]_n or [Zn(Br-BDC)(MIPMO)]_n, (I), has been synthesized by the solvothermal method using 5-bromoisophthalic acid (Br-H₂BDC), bis[4-(2-methyl-1H-imidazol-1-yl)phenyl]methanone (MIPMO) and Zn(NO₃)₂·6H₂O. Structure analysis showed that compound (I) displays twofold parallel interwoven sql nets. Fluorescence experiments confirmed that the compound can sensitively and selectively detect nitrofurantoin (NFT) in aqueous medium. In addition, the possible fluorescence quenching mechanisms of compound (I) toward NFT are investigated.
