Facile synthesis of a fluorescent probe based on a terbium-based metal–organic framework for selective detection of Fe(iii) and Al(iii)

Abstract

It is critical to detect Fe3+ and Al3+ rapidly and accurately due to their high risk to human and ecological environment. In this work, a kind of Terbium-based metal-organic framework...

Construction of a Sensitive Fluorescence Sensor for Convenient 1-HP and UA Detection Relied on a Stable Eu-MOF

“…Compared with the traditional methods for 1-hydroxypyrene and uric acid detection, such as high-performance liquid chromatography, mass spectrometry, electrochemical sensor technologies, and colorimetric method, which are constrained to their insuperable deficiencies including expensive instruments, intricate pretreatment processes, nonreal-time detection, − chemical sensors constructed from metal–organic frameworks (MOFs) have received extensive attention profited from their fascinating advantages: simple synthesis, modifiable structure, high selectivity, and real-time detection. − Among the MOFs, lanthanide-centered MOFs (Ln-MOFs) feature the attractive superiorities combining the Ln­(III) ions with MOFs, such as high specific surface area, adjustable pore volume, characteristic luminescence emission, long lifetimes, and high quantum yields. , In virtue of these charming properties, fluorescent probes relied on Ln-MOFs have been extensively developed and devoted to sensing various substances, including metal ions, − anions, − amino acids, − antibiotics, − biomarkers, − etc.…”
