Lomefloxacin hydrochloride (LMFX) and sodium salicylate (SS) are important targets for real-time detection due to their widespread uses in daily life; accurate and portable monitoring of LMFX and SS is crucial for human health concerns accordingly. Developing a precise and smart platform for determination of the above analytes remains a significant challenge. Herein, a high-sensitivity platform incorporating a luminescence electrospinning film, self-designed smart-phone app, and portable 3D printing device has been developed to identify LMFX and SS. In this work, two heterometallic coordination polymers with two-dimensional layer structures have been synthesized based on 2,2′-oxidiacetic acid ligand (H2oda), namely, [LnPb(oda)2(CH3COO)]n [Ln = Eu (IMU-1); Tb (IMU-2)]. IMU-1 and IMU-2 were ratio-dependent luminescence probes, which could selectively and sensitively sense with LMFX and SS, respectively. Additionally, the synthesized electrospinning films incorporating IMU-1 and IMU-2 were employed to identify LMFX and SS. Both films could rapidly photograph and color-capture through a portable 3D printing device, along with a self-designed smart-phone app that enabled convenient and quick determination of the concentrations of the above analytes. Remarkably, the mechanism exploration indicated that electron transfer from ligands to analytes affected the antenna effect and further utilized the intrinsic luminescence of analytes along with the luminescence quenching of Ln3+ ions. Furthermore, a strategy for constructing ratio-based fluorescent probes by exploiting the luminescence of analytes and Ln3+ ions in host coordination polymers is proposed. This work provides a new insight by combining luminescence probes, portable devices, and a smart-phone app for real-time detection of drugs and food additives.

用智能手机构建比率依赖性配位聚合物探针及其薄膜检测盐酸洛美沙星和水杨酸钠的策略
盐酸洛美沙星 (LMFX) 和水杨酸钠 (SS) 由于在日常生活中的广泛应用,是实时检测的重要靶点;因此,准确、便携地监测 LMFX 和 SS 对于人类健康问题至关重要。开发一个精确、智能的平台来测定上述分析物仍然是一项重大挑战。在此,开发了一个结合了发光静电纺丝薄膜、自主设计的智能手机应用程序和便携式 3D 打印设备的高灵敏度平台,用于识别 LMFX 和 SS。在本工作中,基于 2,2′-氧化二乙酸配体 (H2oda) 合成了两种具有二维层结构的异金属配位聚合物,即 [LnPb(oda)2(CH3COO)]n [Ln = Eu (IMU-1);Tb (IMU-2)]。IMU-1 和 IMU-2 是比率依赖性发光探针,分别能用 LMFX 和 SS 进行选择性和灵敏的传感。此外,采用结合 IMU-1 和 IMU-2 的合成静电纺丝薄膜来识别 LMFX 和 SS。两种胶片都可以通过便携式 3D 打印设备以及自行设计的智能手机应用程序快速拍照和彩色捕获,从而方便快捷地测定上述分析物的浓度。值得注意的是,机理探索表明,电子从配体到分析物的转移影响了天线效应,并进一步利用了分析物的本征发光以及 Ln3+ 离子的发光猝灭。 此外,还提出了一种通过利用宿主配位聚合物中分析物的发光和 Ln3+ 离子来构建基于比率的荧光探针的策略。这项工作通过结合发光探针、便携式设备和智能手机应用程序来实时检测药物和食品添加剂,从而提供了新的见解。
