| Popis: | Trabajo presentado en el 1er Simposio sobre propiedades y aplicaciones de MOFs y COFs, celebrado en Granada (España) del 9 al 10 de abril de 2015. Chemistry of Metal-Organic Frameworks is extraordinar ily rich. However, this richness has been scarcely exploited in their syntheses , which are still widely dominated by environmentally not benign procedures including solvothermal treatments, harmful solvents, etc. This work focuses on changing practically the only parameter that has not been altered in the synthesis of MOFs, i.e. the protonated nature of the linker source. lnstead, alkaline salts of organic linkers have been used. This approach resulted in affording MOF materials in a rapid, cheap and environmentally friendly way [1,2]. allowing for the first time the preparation of high-quality carboxylate-based MOFs under particularly sustainable conditions including room temperature and water as the unique solvent. These and sorne other advantages of this methodology with respect to the conventional ones are summarized in Figure 1 for the case of the MIL-53(AI) material. Amongst sorne other advantages , it is noteworthy to note that the preparation of this material is free of any linker molecules, avoiding the subsequent calcination step, which is compulsory in the conventiona l MIL-53(AI) materials. |
