Two new coordination polymers, namely, [Zn₂(ctpy)₂(bdc)]_n (1) and [Zn(ctpy)(suc)_0.5]_n (2) (Hctpy ​= ​2,2’:6’2’’-terpyridine-4’-carboxylic acid, H₂bdc ​= ​1,4-benzene dicarboxylic acid, H₂suc ​= ​succinic acid) have been synthesized under solvothermal condition. Structural analysis reveals that complexes 1 and 2 exhibit 1D ladder chain structures formed with the coordinated Zn(II) and Hctpy as ladder chains and the coordinated H₂bdc/H₂suc as the bars. The neighbouring chains are further linked by π … π packing to form 2D layer structures. Both the two complexes show highly selective detection of 2,4,6-trinitrophenol, 2,4-dinitrophenol, 4-nitrophenol and 2-nitrophenol from benzene based nitroaromatics (NACs), and efficient removal of Congo Red (CR) from aqueous solution.

两个新的配位聚合物，即，[锌₂（ctpy）₂（BDC）] _Ñ（1）并且，[Zn（ctpy）（SUC）_0.5 ] _Ñ（2）（Hctpy = 2,2' ：6'2在溶剂热条件下合成了''-叔吡啶-4'-羧酸，H ₂ bdc = 1,4，苯二甲酸，H ₂ suc =琥珀酸）。结构分析表明，配合物1和2具有一维梯形链结构，其中配位的Zn（II）和Hctpy为梯形链，配位的H ₂ bdc / H ₂像酒吧一样。相邻链通过π…π堆积进一步链接，以形成2D层结构。两种络合物均显示出从基于苯的硝基芳族化合物（NAC）中对2,4,6-三硝基苯酚，2,4-二硝基苯酚，4-硝基苯酚和2-硝基苯酚的高度选择性检测，以及从水溶液中有效去除刚果红（CR） 。
