Fluorescence recognition of adenosine triphosphate and uric acid by two Eu-based metal–organic frameworks

Abstract

Two Eu-based MOF fluorescent sensors, Eu2(CHDA)2(C2O4)(H2O)4 (1) (CHDA = 1,4-cyclohexanedicarboxylic acid, C2O4 = oxalate group) and Eu2(PDA)3(H2O)3 (2) (p-Phenylenediacetic acid = PDA), were prepared for the rapid detection of uric...

Pyrazine functionalization to boost the antenna effect in rare-earth metal–organic frameworks for tetracycline detection

“…S77 and S78 †). 42,43 However, the luminescence quantum yield (QY) and emission intensity of JNU-205-Eu are lower than those of many of the reported Eu-MOFs, likely due to the less efficient absorption of excitation light from the BTEB linker. To boost the antenna effect, we decided to use pyrazine functionalization to promote energy transfer from the linker to the metal.…”

Recent advances in structures and applications of coordination polymers based on cyclohexanepolycarboxylate ligands

“…For instance, Wang's group presented a new strategy for modular assembly of metal–organic supercontainers using 1,3,5-CHTC and sulfonylcalixarene. 56 Other O-donor auxiliary ligands, such as oxalate 27 d ,52 a ,57 and formate, 27 g ,28,52 b are usually converted in situ under hydrothermal reactions.…”

“…In general the origins of the luminescence properties include organic ligands, coordinated metal ions, guest molecules, and supramolecular interactions. Since no aromaticity for CHPC ligands results in relatively weak emission, the luminosity of those CPs would be predominantly from auxiliary ligands, especially the ones with a large conjugated system, or metal ions such as lanthanide 28,50,52,57,64 d and uranium ions. 27 Moreover, the visual presentation of luminescent CPs would make them ideal for molecular recognition.…”

A Novel Turn-On Fluorescence Probe Based on Cu(II) Functionalized Metal–Organic Frameworks for Visual Detection of Uric Acid

“…Fluorescent probes have been rapidly developed and have widely received increasing attention [ 25 , 26 , 27 , 28 ], because of their distinctive advantages, including easy modification, adjustable luminescence, good biocompatibility, facile operation, use of simple instrumentation, excellent analysis sensitivity, fast response, and highly sensitive fluorescence. Owing to their prominent fluorescence properties, lanthanide rare-earth metal–organic frameworks have been made for UA detection [ 29 , 30 , 31 ].…”
