Acetic acid is an inexpensive and environmentally friendly solvent for facile, clean and high-yielding aryl amination of cyanuric chloride with aromatic amines, including nitroanilines. Aryl amination in acetic acid medium and isolation protocol are greatly simplified as compared to previously reported procedures. Under proper conditions, it is possible to attach the same or different aniline residues

materials, metal nanoparticles@MOF catalyst has been a popular research direction. Herein, we have synthesized a new 3D cobalt metal-organicframework [Co(TATAB)(344-pytpy)·DMF]n(H3TATAB = 4,4',4″-s-triazine-1,3,5-triyltri-p-aminobenzoic acid; 344-pytpy = 4'-(3-pyridyl)-4,2':6',4″-terpyridine)(1)(P1) by solvothermal method. Its crystal structure was determined with single-crystal X-ray diffraction (SC-XRD)

We prepared a rare thorium metal–organic framework (MOF) (Th-TATAB) with a double-walled tetrahedral cage structure and giant unit cell volume of 43 513 Å3, which is the largest of all reported thorium-based MOFs to our knowledge. The unique structural character allows the thorium-based MOF to exhibit exceptional adsorption properties toward I2 and dyes with different charges. The experimental results show that in cyclohexane solution the absorption ability of Th-TATAB toward I2 can reach about 750 mg/g, and especially the removal efficiency in cyclohexane solution (0.01 mol/L) can reach 90% in 3 h, which far exceeded that of reported [Zn2(tptc)-(apy)2-x(H2O)x]·H2O (80%, 48 h) and MIL-101-NH2 (90%, 30 h). Furthermore, the simultaneous removal of molecules with different charges is very challenging, while Th-TATAB displays excellent adsorption properties for anionic, neutral, and cationic dyes individually and simultaneously from aqueous solution. The exploration of the adsorption performance of MOF Th-TATAB for iodine in cyclohexane solution and dye contaminants in aqueous solution is of great significance for environmental aspects, which provides a new strategy for opening up the potential applications of thorium-based MOFs and understanding actinides chemistry.
