A smart sensing triazine hexacarboxylic metal–organic skeleton material: synthesis, structure and multifunctional fluorescence detector

Abstract

A novel lanthanide metal organic framework [(NH2(Me)2)]6·[Tb3(TDPAT)22-O)1.5]·3EtOH·7.5H2O (complex 1) was constructed via the reaction of 5,5′,5′′-(1,3,5-triazine-2,4,6-triyltriimino) tris(azanediyl) triisophthalate (H6TDPAT) and TbCl3·6H2O. It was well characterized by single-crystal X-ray diffraction, IR spectroscopy, UV-vis spectroscopy, elemental analysis, powder X-ray diffraction (PXRD) and thermogravimetric analysis (TG). Structural analysis confirmed that complex 1 is composed of binuclear building blocks [Tb2(COO)122-O)] connected by a triazine hexacarboxylic skeleton, which showed an interesting three-dimensional microporous structure. In addition, the fluorescence properties of complex 1 were explored at room temperature. Surprisingly, the results illustrate that complex 1 has outstanding fluorescence properties and can be used as a multifunctional sensor to selectively detect colchicine, some anions, Fe3+ and nitro compounds. Most notably, the detection of colchicine can still be carried out under biological conditions. To our best knowledge, this is the first example of multifunctional fluorescence sensing properties based on the metal organic framework of Tb3+ and triazinehexacarboxylic acid.
