Abstract

A new two-dimensional coordination polymer (2D CP) {[Cd(Br-BDC)₂(DABCO)₂(DMF)]·0.5DMF}_n (BrCP-1; Br–H₂BDC = 2-bromo-1,4-benzenedicarboxylic acid and DABCO = 1,4-diazabicyclo[2.2.2]octane) was synthesized via the solvothermal reaction. Interestingly, the BrCP-1 exhibits strong luminescent property in pure aqueous media as well as in the solid state over an extended period when excited at 320 nm, emitting at 425 and 458 nm. The high luminescent property was explored for the rapid detection of tetracycline antibiotics and nitroaromatic (NAC) explosives in real-world environmental samples, including milk, river water, and soil samples. The UV–vis and fluorescence spectroscopic studies were performed to explain the resonance energy transfer and inner filter effect sensing mechanism accurately. Besides, the correction intensity (I_corr) for each analyte and correct quenching efficiency (QE_corr) were also evaluated. The density functional theory (DFT) experiment was also performed to evaluate the theoretical energy profile of respective tetracycline antibiotics and NACs, which established a proper photoinduced electron transfer (PET) mechanism.

利用二维配位聚合物对现实世界基质中的四环素类和硝基芳香族化合物进行内滤效应可控检测的战略进展

通过溶热反应合成了一种新的二维配位聚合物（2D CP）{[Cd(Br-BDC)2(DABCO)2(DMF)]-0.5DMF}n（BrCP-1；Br-H2BDC = 2-溴-1,4-苯二甲酸，DABCO = 1,4-二氮杂双环[2.2.2]辛烷）。有趣的是，BrCP-1 在纯水介质中以及固态下，在 320 纳米波长处激发时，在 425 纳米和 458 纳米波长处发光，并在较长时间内表现出强烈的发光特性。研究人员利用这种高发光特性快速检测了实际环境样品（包括牛奶、河水和土壤样品）中的四环素类抗生素和硝基芳香族（NAC）炸药。紫外-可见光谱和荧光光谱研究准确解释了共振能量转移和内滤光片效应的传感机制。此外，还对每种分析物的校正强度（Icorr）和正确淬灭效率（QEcorr）进行了评估。此外，还进行了密度泛函理论（DFT）实验，以评估四环素类抗生素和 NAC 的理论能量曲线，从而建立了正确的光诱导电子转移（PET）机制。
