abstract Two new ternary Cd(II) coordination polymers (CPs), -[Cd-2(L)(mip)(2)center dot 2H(2)O](n) (1) and {[Cd-2(L)(hip)(2)].3.5H(2)O}(n) (2) (L = 1,4-bis(thiabendazol-1-ylmethyl)benzene, -H(2)mip = 5-methylisophthalic acid, H(2)hip = 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 pi-pi 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 mu M and 0.21 mu M, separately, whereas the LODs of 2 for BZH and MnO4- are 1.30 mu M and 1.95 mu M, respectively.
