利用羧酸配体合理设计沸石型四氮唑框架及其快速吸附碘
Rational Design of Zeolitic Tetrazolate Frameworks with Carboxylate Ligands for Rapid Accumulation of Iodine
摘要
Abstract
Zeolitic metal-organic frameworks(MOFs) with high porosity, controlled pore size, regular pore shape, high thermal and chemical stability have been extensively studied and display potential applications in the field of rapid accumulation of iodine.Here, through simulating the structure of zeolite, two tetrahedral tetrazolate frameworks(TTF-8 and TTF-9) were successfully assembled via using thiophene-2,5-dicarboxylate and 4,4′-oxybisbenzoic acid as an auxiliary ligand, respectively.The results of single-crystal X-ray diffraction measurement show that TTF-8 crystallizes in a tetragonal space group of P42mc, while TTF-9 exhibits a monoclinic space group of P21/c.Remarkably, although TTF-8 and TTF-9 exhibit the same BCT topology, their frameworks and pore structures are entirely different.Two TTFs materials display outstanding performance on rapidly enriching iodine.关键词
