A Fluorescent Chlorin Based Metal Organic Framework for Rapid and Selective Sensing of ﬂuoride Ions

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.
