Abstract

Two lanthanide MOFs based on 3,3′-((2,3,6,7-tetramethoxyanthracene-9,10-diyl)bis(4,1-phenylene))diacrylic acid (H₂L^OMe), [Eu(L^OMe)_1.5(H₂O)₂]·3.5DMA·2H₂O (1) and [Pr(L^OMe)(H₂O)₄]·2.5DMA·3H₂O (2) were synthesized under solvothermal conditions. Complex 1 displayed a 2D net with single nodal 4⁴-sql topology, which further formed a 3D supramolecular architecture by strong π⋯π interaction. Complex 2 featured a 3D open framework with {4²·8⁴}-PtS topology. The PL spectrum results showed that 2 has potential application not only in the sensing of small organic molecules, such as DMF and NB, but also in detecting Al³⁺ and nitroaromatic derivatives. Furthermore, 2 also showed the selective adsorption of CO₂ over CH₄ and high catalytic activities with the cyanosilylation reaction.
