Abstract

A new ionic cobalt(II) chain coordination polymer, {[Co(bbbm)(H2O)4]·ATBIP·2DMA·2H2O}n (Co-CP) with the multi-functional 5-amino-2,4,6-tribromoisophthalic acid (H2ATBIP) and flexible linker 1, 4-bis(benzimidazole-1-methyl)benzene (bbbm) was prepared with convenient slow evaporation method. Moreover, its composite with hydroxyl carbon nanotubes (CNTs) (Co-CP@CNTs) was constructed by “one pot” synthesis. Co-CP further assembles into a 3D supramolecular framework with 1D channels with the aid of the hydrogen-bonded tape. The amperometric response demonstrates that Co-CP/GCE and Co-CP@CNTs/GCE show sensitive and selective electrochemical oxidation sensing to ascorbic acid (AA) and reduction sensing to Fe3+ in 0.1 M H2SO4, respectively. Moreover, Co-CP@CNTs exhibits better electrocatalytic capability for the oxidation sensing of AA and reduction sensing of Fe3+ than that of Co-CP. Remarkably, the strategy was successfully applied in the portable screen-printed electrode (SPE). Among three electrodes, the Co-CP@CNTs/SPE shows the most rapid and sensitive sensing with the largest exponential range of 0.01 - 26 mM for AA and 0.01 - 21 mM for Fe3+, respectively. The limits of detection (LOD) reach to 0.74 μM (AA) and 0.96 μM (Fe3+) for Co-CP@CNTs/GCE, 0.32 μM (AA) and 0.91 μM (Fe3+) for Co-CP@CNTs/SPE, respectively. Furthermore, the portable Co-CP@CNTs/SPE has been successfully used as a platform for the practical detection of AA and Fe3+ in the real-world samples.

构建新型离子型 Co(II) 配位聚合物及其与 CNT 的复合材料,显示出对 AA 和 Fe3+ 的双重电化学传感能力
采用简便的缓慢蒸发法制备了一种新型离子钴(II)链配位聚合物{[Co(bbbm)(H2O)4]-ATBIP-2DMA-2H2O}n(Co-CP),该聚合物含有多功能 5-氨基-2,4,6-三溴间苯二甲酸(H2ATBIP)和柔性连接剂 1,4-双(苯并咪唑-1-甲基)苯(bbbm)。此外,还通过 "一锅 "合成法构建了其与羟基碳纳米管(CNTs)的复合材料(Co-CP@CNTs)。借助氢键带,Co-CP 进一步组装成具有一维通道的三维超分子框架。安培响应表明,Co-CP/GCE 和 Co-CP@CNTs/GCE 在 0.1 M H2SO4 中分别对抗坏血酸(AA)和 Fe3+ 具有灵敏和选择性的电化学氧化传感和还原传感。此外,与 Co-CP 相比,Co-CP@CNTs 对 AA 的氧化传感和 Fe3+ 的还原传感具有更好的电催化能力。值得注意的是,该策略已成功应用于便携式丝网印刷电极(SPE)。在三种电极中,Co-CP@CNTs/SPE 的传感速度最快,灵敏度最高,对 AA 和 Fe3+ 的指数范围分别为 0.01 - 26 mM 和 0.01 - 21 mM。Co-CP@CNTs/GCE 的检测限(LOD)分别达到 0.74 μM(AA)和 0.96 μM(Fe3+),Co-CP@CNTs/SPE 的检测限(LOD)分别达到 0.32 μM(AA)和 0.91 μM(Fe3+)。此外,便携式 Co-CP@CNTs/SPE 已成功用作实际检测真实世界样品中 AA 和 Fe3+ 的平台。

期刊介绍: The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
