Abstract: In the present study, open metal site iron-based MOF [MIL-100(Fe)], by a solvothermal method with polygonal morphology, are synthesised and then applied as a heterogeneous green catalyst for aza-Michael addition of various amines with α, β-unsaturated compounds. The MIL-100(Fe) was found to be efficient, selective, green and heterogeneous catalyst for the aza-Michael reaction. The proposed catalyst has better recyclability and can be reused six times without apparent loss of activity. Graphical Abstract: [Figure not available: see fulltext.].

The selectivity and sensitivity of a pH stable hetarylazo dye equipped with binding sites consisting of N, S and N, O combinations, towards Hg2+ and Fe3+ over a large number of other cations including lanthanides, is described. Hg2+ and Fe3+ ions coordinate to the dye through N, S binding site forming 2:1 and 1:1 complexes, respectively. Distinct naked-eye color changes for both Hg2+ (yellow to purple) and Fe 3+ (yellow to red) were quantified for simultaneous estimation of these ions. To further establish the binding and sensing phenomenon, another analogous hetarylazo dye lacking N, O combination was evaluated and found to give similar results. For practical applicability in routine life, very handy and ready-to-use paper strips coated with the dye have been prepared for the detection of Hg2+, just like the pH paper strips.
