Two Luminescent Lanthanide-Organic Frameworks Containing Bithiophene groups for selective detection of Nitrobenzene and Fe3+

Abstract

Two lanthanide-organic frameworks formulated as [Eu2(DMTDC)3(DEF)4]·DEF·6H2O (1) and [Tb2(DMTDC)3(DEF)4]·DEF·6H2O (2) (H2DMTDC = 3,4-dimethylthieno[2,3-b]thiophene-2,5-dicarboxylic acid and DEF = N,N-diethylformamide) have been synthesized under solvothermal conditions by using a bithiophene dicarboxylate organic ligand H2DMTDC. Compounds 1 and 2 are isomorphous, and feature 3D frameworks with uninodal six-connected pcu -Po topology structures. The systematic luminescent experiments reveal that 1 and 2 can be used as fast-response fluorescence sensors for sensitive detection of nitrobenzene and Fe3+ ions with favorable recyclability through fluorescence quenching.
