文摘

The metal-organic frameworks (MOFs), {[Cd(L)(H₂O)]·CH₃OH·DMF} (1) and [Pb(L)(DMF)] (2) (L = 2,4-dihydroxybenzaldehyde nicotinoylhydrazone), were synthesized and characterized using microanalyses, IR spectroscopy, and single-crystal X-ray diffraction. Single crystal X-ray analyses revealed that both 1 and 2 exhibit 2D grid networks. The photoluminescence investigation indicates that 1 and 2 could be a prospective candidate for developing luminescencent sensors for the selective sensing of nitrobenzene, which is used as a precursor for explosives. The luminescent properties of 1 and 2 in different solvents were investigated and corroborated by theoretical calculations. Additionally compounds 1 and 2 also show selective sensing ability for Fe³⁺ as well as for CrO₄^2– ions.
