Abstract

A new ternary coordination polymer (CP), {[Cd(L)(nip)(H₂O)]·H₂O}_n (1) (L = 1,6-bis(benzimidazol-2-yl)hexane, H₂nip = 5-nitroisophthalic acid), was hydrothermally synthesized and characterized. 1 is a two-dimensional sheet and extends into three-dimensional supramolecular networks through O-H···O hydrogen bonding interactions, which displays high thermal and pH stabilities. 1 demonstrated notable selectivity, sensitivity, and reusability for the luminescent sensing of chlortetracycline (CTC) and Fe³⁺ ions. Density functional theory calculations and UV−Vis absorption spectroscopy were employed to investigate the possible sensing mechanisms.

Graphical Abstract

A new Cd(II) metal coordination polymer, namely {[Cd(L)(nip)(H₂O)]·H₂O}_n can act as a sensitive luminescent probe for chlortetracycline (CTC) and Fe³⁺ ions in water with excellent selectivity and recyclability.

用于水溶液中金霉素和 Fe3+ 离子发光传感的新型水稳定镉（II）配位聚合物

一种新的三元配位聚合物（CP）{[Cd(L)(nip)(H2O)]-H2O}n (1)（L = 1,6-双(苯并咪唑-2-基)己烷，H2nip = 5-硝基间苯二甲酸）通过水热法合成并表征。1 是一个二维薄片，并通过 O-H-O 氢键相互作用扩展成三维超分子网络，具有很高的热稳定性和 pH 稳定性。1 对金霉素（CTC）和 Fe3+ 离子的发光传感具有显著的选择性、灵敏性和可重复使用性。图解摘要一种新的镉(II)金属配位聚合物，即{[Cd(L)(nip)(H2O)]-H2O}n，可用作水中金霉素（CTC）和 Fe3+ 离子的灵敏发光探针，具有极佳的选择性和可回收性。

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
