Abstract
Two new ternary Cd(II) coordination polymers (CPs), [Cd2(L)(mip)2·2H2O]n (1) and {[Cd2(L)(hip)2]·3.5H2O}n (2) (L = 1,4-bis(thiabendazol-1-ylmethyl)benzene, H2mip = 5-methylisophthalic acid, H2hip = 5-hydroxyisophthalic acid), have been synthesized and characterized by physicochemical and spectroscopic methods. 1 possesses a 1D chained structure while 2 exhibits a 2D hcb layer. Both CPs can be further extended into 2D/3D supramolecular frameworks via π–π stacking interactions. Both 1 and 2 can serve as dual-responsive luminescent probes for the selective detection of benzaldehyde (BZH) and permanganate anions (MnO4−) in aqueous system. The limits of detection (LODs) of 1 for BZH and MnO4− are 0.13 µM and 0.21 µM, separately, whereas the LODs of 2 for BZH and MnO4− are 1.30 µM and 1.95 µM, respectively.

摘要
两种新的三元 Cd(II) 配位聚合物 (CPs)，[Cd 2 (L)(mip) 2 ·2H 2 O] n ( 1 ) 和 {[Cd 2 (L)(hip) 2 ]·3.5H 2 O } n ( 2 ) (L = 1,4-bis(thiabendazol-1-ylmethyl)benzo, H 2 mip = 5-methylisophthalic acid, H 2 hip = 5-hydroxyisophthalic acid), 已合成并通过物理化学和光谱表征方法。1具有一维链状结构，而2具有二维hcb层。两个 CP 都可以通过以下方式进一步扩展到 2D/3D 超分子框架中π – π堆积相互作用。既1和2可以作为双响应发光探针为苯甲醛的选择性检测（BZH）和高锰酸盐阴离子（MnO的4 - ）在水溶液系统。BZH 和 MnO 4 - 1的检测限 (LOD)分别为 0.13 µM 和 0.21 µM，而BZH 和 MnO 4 - 2的 LOD分别为 1.30 µM 和 1.95 µM。
