The concentration of Zn2+ is closely related to the ecological environment and physical health and must be monitored conveniently and accurately. Herein, a novel coordination polymer, namely, {[Cd2L2(bpy)2]·H2O·0.25DMF}n (CP-1, bpy = 2,2′-bipyridine, H2L = 5-(1H-1,2,4-triazole-1-yl)-1,3-phthalic acid) was synthesized under solvothermal conditions and can be used for selective detection of Zn2+ with an extremely low detection limit. Single-crystal X-ray diffraction analyses revealed that CP-1 exhibits an interspersed two-dimensional (2D) layer and further constitutes a 3D layer by weak interactions. Fluorescence experiments showed that CP-1 can be used as an excellent fluorescent sensor for selectively detecting Zn2+ with the detection limit as low as 0.073 μM. In addition, CP-1 can also be used for the efficient detection of Cr2O7 2– and phenylglyoxylic acid (PGA) with detection limits of 0.68 and 1.59 μM respectively. Moreover, the mechanism study showed that the turn-on behavior of CP-1 for detecting Zn2+ can be attributed to absorbance-induced enhancement (ACE), and the turn-off behavior for detecting Cr2O7 2– and PGA can be attributed to the “internal filtering effect” (IFE) and the combined effect of photoinduced electron transfer (PET) and competitive absorption, respectively.

A Dy(III) coordination polymer (CP), [Dy(spasds)(H2O)2]n (1) (Na2Hspasds = 5-(4-sulfophenylazo)salicylic disodium salt), has been synthesized using a hydrothermal method and characterized. 1 features a 2D layered structure, where the spasda3− anions act as pentadentate ligands, adopting carboxylate, sulfonate and phenolate groups to bridge with four Dy centers in η3-μ1: μ2, η2-μ1: μ1, and monodentate coordination modes, respectively. It possesses a unique (4,4)-connected net with a Schläfli symbol of {44·62}{4}2. The luminescence study revealed that 1 exhibited a broad fluorescent emission band at 392 nm. Moreover, the visual blue color has been confirmed by the CIE plot. 1 can serve as a dual-functional luminescent sensor toward Fe3+ and MnO4− through the luminescence quenching effect, with limits of detection (LODs) of 9.30 × 10−7 and 1.19 × 10−6 M, respectively. The LODs are relatively low in comparison with those of the reported CP-based sensors for Fe3+ and MnO4−. In addition, 1 also has high selectivity and remarkable anti-interference ability, as well as good recyclability for at least five cycles. Furthermore, the potential application of the sensor for the detection of Fe3+ and MnO4− was studied through simulated wastewater samples with different concentrations. The possible sensing mechanisms were investigated using Ultraviolet-Visible (UV-Vis) absorption spectroscopy and density functional theory (DFT) calculations. The results revealed that the luminescence turn-off effects toward Fe3+ and MnO4− were caused by competitive absorption and photoinduced electron transfer (PET), and competitive absorption and inner filter effect (IFE), respectively.
