Rani, Pooja; Gauri; Husain, Ahmad; Bhasin, K. K.; Kumar, Girijesh published the artcile< A Doubly Interpenetrated CuII Metal-Organic Framework for Selective Molecular Recognition of Nitroaromatics>, COA of Formula: C6H8N2, the main research area is copper pyridinylnaphthalenecarboxamide oxybisbenzoate MOF preparation thermal stability fluorescent sensor; crystal structure copper pyridinylnaphthalenecarboxamide oxybisbenzoate MOF.
Herein, we report the design, synthesis, and structural characterization of a novel 2-fold interpenetrated CuII metal-organic framework Cu-MOF-1 [{Cu2(L)(oba)2}·DMF·H2O]α (where, L = N2,N6-di(pyridin-4-yl)naphthalene-2,6-dicarboxamide and oba2- is 4,41-oxybis(benzoic acid) anion). A single-crystal X-ray anal. reveals that Cu-MOF-1 exhibits a doubly (1 + 1) interpenetrated three-dimensional structure with 6-connected mab topol. Moreover, Cu-MOF-1 showed high fluorescence stability in methanol solution and selectively detected nitroaroms. with high quenching constants and low detection limits of 0.31 × 105 M-1 and 22.65μM for 2,4,6-TNP; 1.34 × 105 M-1 and 18.7μM for 4-NPH; and 1.49 × 105 M-1 and 14.07μM for 4-NA. Notably, ligand L itself did not display any type of recognition for any nitroaroms. in methanol solution The sensing of NACs by Cu-MOF-1 followed mostly the resonance energy transfer mechanism; however, in the case of 4-NPH and 2,4,6-TNP an electron transfer mechanism also exists. Importantly, Cu-MOF-1 shows recyclability up to five cycles without any significant loss in quenching efficiency.
