摘要

灵敏、快速、便捷地检测 2,6-吡啶二羧酸(DPA,炭疽杆菌生物标记物)对于炭疽病的筛查和诊断至关重要。基于金属有机框架(MOF)的传感器在传感 DPA 方面大有可为,但设计和构建具有高特异性和高灵敏度的高性能传感器仍具有挑战性。本研究组装了一种新型发光羧酸盐 MOF(TTCA-Zn),并将其用于 DPA 的特异性识别。研究发现,它具有以[NH2(CH3)2]+ 为反离子的 sqc 拓扑三维阴离子框架结构。加入 DPA 后,TTCA-Zn 的荧光强度显示出 "开启 "响应,可在 0 至 70 μM 的宽范围内作为 DPA 的高性能荧光感应器,检测限低至 14 nM。此外,还对其传感机制进行了系统研究。这项工作不仅报道了一种新的 DPA 荧光传感材料,还为此类传感器的结构设计、组装和应用提供了一种策略。

Rational fabrication of an anionic zinc carboxylate framework as a fluorescent probe for 2,6-pyridinedicarboxylic acid†

Sensitive, rapid and convenient sensing of 2,6-pyridinedicarboxylic acid (DPA, a biomarker for Bacillus anthracis) is crucial for the screening and diagnosis of anthrax. Metal organic framework (MOF)-based sensors are very promising for sensing DPA; however, the design and construction of high-performance sensors with high specificity and sensitivity is still challenging. In this work, a novel luminescent carboxylate MOF (TTCA-Zn) was assembled and employed specifically for the recognition of DPA. We found that it has a three-dimensional anionic framework structure with sqc topology and uses [NH2(CH3)2]+ as the counter ions. The fluorescence intensity of TTCA-Zn displays a “turn-on” response to the addition of DPA and can function as a high-performance fluorescent sensor of DPA over a wide detection range of 0 to 70 μM, with a low detection limit of 14 nM. The sensing mechanism is also systematically investigated. This work not only reports a new fluorescence sensing material for DPA, but also provides a strategy for the structural design, assembly, and application of such sensors.
