A water-stable Cd-MOF and corresponding MOF@melamine foam composite for detection and removal of antibiotics, explosives, and anions

Metal–organic frameworks (MOFs) as fluorescence sensors: principles, development and prospects

“…For example, when the energies of the ligands and the lanthanide ions do not match very well, an incomplete "antenna effect" results in the sensors having both ligand-based and metal-based fluorescent signals. 21,52,53…”

Cu(ii) and Zn(ii) frameworks constructed by directional tuning of diverse substituted groups on a triazine skeleton and supermassive adsorption behavior for iodine and dyes

“…In our work, 200 ppm of iodine cyclohexane solution was prepared to explore the iodine adsorption capacity of the compounds. Different doses (10,20,30,40 and 80 mg) of complexes 1 and 2 were, respectively, soaked in cyclohexane solution of iodine (10 mL 200 ppm) at 25 °C. Also, the adsorption performance of complex 3 was explored.…”

“…13,14 Because of their excellent porosity, tunable pore size, they are good candidates for magnetism, gas adsorption/separation, luminescence and sensing, electrochemical and catalysis and so on. [15][16][17][18][19][20][21][22][23][24][25] Generally, organic ligands are divided into two categories: polycarboxylic acids and nitrogen heterocycles. Among them, triazine polycarboxylic acid ligands are the representatives of the series of polycarboxylic acid ligands, which are widely used in the synthesis of metal-organic coordination polymers.…”

A Eu(iii) metal–organic framework based on anthracenyl and alkynyl conjugation as a fluorescence probe for the selective monitoring of Fe3+ and TNP

“…In recent years, luminescent metal–organic frameworks have become the subject of much attention due to their numerous tunable sites, fast response time, and high sensitivity. 21,22 Lanthanide metal–organic frameworks (Ln-MOFs) are very popular and have been widely used as luminescent sensing materials due to their special optical properties, such as narrow emission peaks, large Stokes shifts, long luminescence lifetimes, and high quantum yields. 23–25 As luminescent sensors, MOFs synthesized from organic linkers and metal ions/clusters are widely used to detect various pollutants, such as metal cations (Ni 2+ , Hg 2+ , Fe 3+ ), 26–28 anions (CrO 4 2− , Cr 2 O 7 2− , MnO 4 − , CO 3 2− ), 29–31 nitro explosives (NB, TNP) 32–34 and antibiotics (nitrofurazone, nitrofurantoin, furazolidone).…”
