Expanding the NUIG MOF family: synthesis and characterization of new MOFs for selective CO2 adsorption, metal ion removal from aqueous systems, and drug delivery applications.

摘要: Metal organic frameworks (MOFs) have attracted considerable attention in recent years due to their use a wide range of environmental, industrial and biomedical applications. The employment benzophenone-4,4'-dicarboxylic acid (bphdcH2) MOF chemistry provided access the 3D mixed metal MOFs [CoNa2(bphdc)2(DMF)2]n (NUIG2) [ZnK2(bphdc)2(DMF)2]n (NUIG3), 2D homometallic [Co2(OH)(bphdcH)2(DMF)2(H2O)2]n(OH)·DMF (1·DMF). 1·DMF is based on dinuclear SBU consists interpenetrating networks with an sql topology. Dc magnetic susceptibility studies were carried out revealed presence weak antiferomagnetic exchange interactions between centres. NUIG2 NUIG3 are structural analogues [ZnNa2(bphdc)2(DMF)2]n (NUIG1), which has shown exceptionally high encapsulation for ibuprophen (Ibu), NO ions. Both display ion (CoII, NiII, CuII) adsorption capacity, comparable that NUIG1, exhibiting good performance Ibu uptake (780 mg per g NUIG2). Monte Carlo simulations conducted NUIG1 order assess its capacity other guest molecules, it possesses outstanding CO2 at ambient pressure, larger than previously reported best functioning species (104 vs. 100 cm3 (stp) cm3). Furthermore, exhibits selectivity over CH4.
