Temperature- and solvent-induced reversible single-crystal-to-single-crystal transformations of Tb^III-based MOFs with excellent stabilities and fluorescence sensing properties toward drug molecules

Abstract

Recently, single-crystal-to-single-crystal conversion has been a hot topic in the field of metal-organic framework (MOF) materials, which could improve the stability and properties due to the structural change. A new...

A pH-Stable TbIII-Based Metal–Organic Framework as a Turn-On and Blue-Shift Fluorescence Sensor toward Benzaldehyde and Salicylaldehyde in Aqueous Solution

“…Fluorescent test strips, LED lamp beads, and composite films were further prepared. The devices were prepared as follows: (I) the test paper was ultrasonically soaked in a JXUST-19 suspension for 30 min and then removed and dried naturally; (II) a mixture of nail polish, finely ground JXUST-19 , and BZ/SA were applied to the surface of commercial LED lamp beads (λ ex = 365 nm); (III) JXUST-19 was uniformly dispersed in poly­(methyl methacrylate) (PMMA) to obtain composite films …”

A {Zn4} cluster as a bi-functional luminescence sensor for highly sensitive detection of chloride ions and histidine in aqueous media

“…A variety of coordinated metal clusters with special structures can be obtained by designing organic ligands and changing the inorganic metal nodes, giving varied functions, 34–36 such as luminescence, magnetism, catalysis, etc. 37–58 Among them, LCMCs have been widely used in the detection of metal ions, nitro explosives and biomolecules because of their well-defined active sites, accurately tailorable structures and excellent luminescent properties, enabling mechanism-based luminescence sensing optimization. 59–65 According to literature studies, there are few reports using LCMCs as luminescence sensors for detecting halide ions or amino acids, especially no bifunctional sensors for halide ions and amino acid determination.…”
