Multifunctional lanthanide-organic frameworks for fluorescent sensing, gas separation and catalysis

Two lanthanide MOFs based on 3,3'-((2,3,6,7-tetramethoxyanthracene-9,10-diyl)bis(4,1-phenylene))di- acrylic acid (H2LOme), [Fu(L-OMe)(1.5),(H2O)(2)].3.5DMA.2H(2)O (1) and [Pr(Cpme)(H2O)(4)center dot 2.5DMA.3H(2)O (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 pi(...)pi interaction. Complex 2 featured a 3D open framework with {4(3).8(4))-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 CO, over CH4 and high catalytic activities with the cyanosilylation reaction.
