摘要
氯丁二烯是一种广泛用于生产氯丁橡胶的单体，1-羟基-2-丁酮（1H2B）是氯丁二烯在尿液中的代谢产物之一，会破坏 DNA 的正常结构和功能，对人体健康产生重大影响。本文以 2,5-呋喃二甲酸（HFDA）和 1,2,4- 三唑（Htrz）混合配体合成了一种三维 Zn 基配位聚合物（）和一种二维 Cd 基配位聚合物（），并对其进行了全面表征。 该聚合物对 1H2B 具有极佳的稳定性和卓越的传感性能，可在 15 秒内快速响应，具有良好的可回收性，检测限为 9.24 μM。此外，在尿液中存在主要共存化合物的情况下，它也具有良好的选择性。对传感机制的深入研究表明，发光传感是基于竞争吸收和光电子转移过程。
Luminescent coordination polymers with mixed carboxylate and triazole ligands for rapid detection of chloroprene metabolite
Chloroprene is a monomer widely used in the production of neoprene, and 1-hydroxy-2-butanone (1H2B) is one of the metabolites of chloroprene in urine, which can place a significant impact on human health by disrupting the normal structure and function of DNA. Herein, a three-dimensional Zn-based coordination polymer (1) and a two-dimensional Cd-based coordination polymer (2) were synthesized with mixed ligands of 2,5-furandicarboxylic acid (H2FDA) and 1,2,4-triazole (Htrz) and fully characterized. 2 exhibits excellent stability and superior sensing performance for 1H2B with fast response within 15 s, good recyclability and a detection limit of 9.24 μM. In addition, 2 demonstrates good selectivity in presence of main coexisting compounds in urine. In-depth investigations of the sensing mechanism revealed that the luminescence sensing is based on the competitive absorption and photoelectron transfer processes.
