Thiazolo[5,4-d]thiazole-2,5-dicarboxylic acid (HThz), a thiazolothiazole (TTz) derivative with carboxylic acid groups, was synthesized as a ligand for the creation of five MOFs, each associated with distinct metal ions including Ag, Mn, Co, Zn, and Cu. The cathodic electrochemiluminescence (ECL) of HThz and the resulting MOFs was investigated. HThz was found to generate ECL signals, but this process was heavily reliant on potassium persulfate (KSO) as a co-reactant.

Flavonoid glycosides are formed by dehydration condensation of aglycones and sugar molecules. Therefore, discrimination of flavonoid glycosides from their corresponding aglycones is a challenging task because they contain the same aglycone part in their molecular structures. Herein, boric acid-functional Eu(III)-organic framework (BA-Eu-MOF) was applied to discriminate flavonoid glycosides including baicalin (Bai), wogonoside (Wog), rutin (Rut), puerarin (Pue), quercitrin (Que) and astragalin (Ast) from their corresponding aglycones for the first time.

Prebiotics and probiotics have key roles in the intervention and treatment of food allergies. This study assesses the effect of synergistic fructo-oligosaccharide (Lp-FOS) intervention using an allergic mouse model induced by soy protein. The results showed that Lp synergistic FOS significantly decreased clinical allergy scores, inhibited specific antibodies (IgE, IgG, and IgG1), IL-4, IL-6, and IL-17A levels, and increased IFN-γ and IL-10 levels.

Metal-organic frameworks (MOFs) can be prepared from oligomeric organic ligands to prepare materials referred to as oligoMOFs. Studies of oligoMOFs are relatively limited, with most existing reports focused on fundamental structure-property relationships. In this report, functional groups, such as terminal alkynes and pyridine groups, are installed on the tether between 1,4-benzene dicarboxylic acid (Hbdc) groups of the dimer ligands.

Two 3D/2D anionic metal-organic frameworks (MOFs), [Cu(HL)] () and [Mn(L)(DMF)] ( (DMF = ,-dimethylformamide), were synthesized by the solvothermal reaction of metal salts and 5'-(4-carboxyphenyl)-2',4',6'-triethyl-[1,1':3',1″-terphenyl]-4,4″-dicarboxylic acid (HL). Single-crystal X-ray diffraction analyses revealed that complex shows three-dimensional (3D) frameworks with a (3,6)-connected 3-fold interpenetrated topology with the Schläfli symbols of {4.6}{4.
