Abstract

Metal organic frameworks (MOFs) have emerged as a highly promising platform for a range of sensing applications due to their tunable structures and diverse functionalities. In this study, we have developed and synthesized a novel chlorin luminescent MOF (TCPC-224), which is composed of 5,10,15,20-tetrakis(4-carboxyphenyl) chlorin ligand and zirconium clusters. TCPC-224 was utilized as a “turn-on” sensing probe for the detection of fluoride ions. The proposed sensing approach demonstrates a strong linear relationship in the range of 0.3–50 μM with a low detection limit of 0.029 μM toward fluoride ions. Furthermore, TCPC-224 has also been applied to detect fluoride ions in complex samples (river and tap water). These findings indicate that TCPC-224 holds great potential to serve as a rapid (less than 3 min), sensitive and selective fluorescent sensing platform for the detection and quantification of fluoride ions.

用于氟离子快速和选择性传感的荧光氯基金属有机框架

金属有机框架（mof）由于其结构可调和功能多样，已成为一系列传感应用的极具前景的平台。在本研究中，我们开发并合成了一种新型的氯发光MOF (TCPC-224)，它由5,10,15,20-四（4-羧基苯基）氯配体和锆簇组成。TCPC-224被用作检测氟离子的“开启”传感探针。该方法在0.3 ~ 50 μM范围内具有较强的线性关系，对氟离子的检测限低至0.029 μM。此外，TCPC-224也被用于检测复杂样品（河流和自来水）中的氟离子。这些发现表明，TCPC-224具有很大的潜力，可作为快速（小于3分钟）、灵敏和选择性的氟离子检测和定量荧光传感平台。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
