Metal ion detection using luminescent-MOFs: Principles, strategies and roadmap

An MOF‐Based Luminescent Sensor Array for Pattern Recognition and Quantification of Metal Ions

“…First, due to the principle of cross‐reaction, the remaining pyridine N sites in the MOFs framework serve as Lewis bases, that can bind to Lewis acids (such as Ag + , Cu 2+ , Fe 3+ , Co 2+ and Ni 2+ ). [ 47 ] As shown in Figure S21, Supporting Information, the high resolution XPS spectrums of N 1s for MOF‐253 after reaction with the five metal ions (MOF‐253⊃M n+ , M n+ = Fe 3+ , Co 2+ , Ni 2+ , Cu 2+ , and Ag + ), all display a new peak (399.72, 399.76, 399.69, 399.87, 399.57 eV, respectively) with higher binding energy compared with MOF‐253 (398.58 eV). It certified the occurrence of the interaction between the five metal ions and pyridine N sites.…”

High-efficient liquid exfoliation of 2D metal-organic framework using deep-eutectic solvents

“…Chemical sensor is an effective method for trace pollutant determination in water. MOFs are good candidates for metal cations and anions sensing due to their tunable topological structures and high porosity [38] , [39] , [40] . Particularly, lanthanide based MOFs (Ln-MOFs) exhibit brilliant performance as luminescent probes owing to their special 4f electronic configurations [41] , [42] .…”

Electrochemical Applications of Ferrocene‐Based Coordination Polymers

“…[3] On the other hand, coordination polymers (CPs) are excellent precursors for the development of a new class of highly tailorable functionalized nanomaterials for gas storage, detection, catalysts, pollutant adsorption, and electrochemical applications. [4][5][6][7][8][9][10][11][12][13] CPs offer an endless variety of metal ion centers and connecting ligands (which can be redoxactive or -inactive and suitable for the construction of one-, two-, or three-dimensional networks), which is ideal for the construction of solid-state redox-active materials for diverse applications. Progress in the field of redox-active CPs is important for both fundamental and applied research, as these materials provide unique insights into charge transfer in the coordination space and exhibit features that may support the future development of useful apparatus.…”

“…The strong interaction between Fe(II) and the cyclopentadienyl rings endows Fc with good thermal stability and tolerance toward oxygen, thus facilitating the synthesis of various Fc derivatives [3] . On the other hand, coordination polymers (CPs) are excellent precursors for the development of a new class of highly tailorable functionalized nanomaterials for gas storage, detection, catalysts, pollutant adsorption, and electrochemical applications [4–13] . CPs offer an endless variety of metal ion centers and connecting ligands (which can be redox‐active or ‐inactive and suitable for the construction of one‐, two‐, or three‐dimensional networks), which is ideal for the construction of solid‐state redox‐active materials for diverse applications.…”
