Multifunctional material of terbium-based metal-organic framework showing fluorescence detection for Hg2+ and proton conductivity

A novel terbium-based metal-organic framework, namely {[(CH3CH2)2NH2]2[Tb2(TTDI)2(H2O)1.7 (HCOOH)0.3]·DEF·3H2O}n (Tb-MOF, H₄TTDI=5-[5-(3,5-dicarboxyphenyl) thieno [3,2-b] thiophen-2-yl] benzene-1,3-dicarboxylic acid ) was synthesized and characterized. Tb-MOF is a three-dimensional porous framework based on binuclear clusters...
