Multi-responsive luminescent sensor based on a stable Eu(III) metal-organic framework for sensing Fe3+, MnO4−, and Cr2O72− in aqueous solution

A new water-stable three-dimensional (3D) Eu(III) metal-organic framework with the formula of {[Eu3(BTDC)4(HCOO)(H2O)2]•solvents}n (JXUST-9) was successfully obtained by the solvothermal reaction of 2,1,3-benzothiadiazole-4,7-dicarboxylic acid (H2BTDC) and Eu(NO3)3•6H2O. The PXRD patterns...
