Synthesis of amine-tagged metal-organic frameworks isostructural to MIL-101(Cr)

Materials that are isostructural to MIL-101(Cr) were obtained from partial replacement of terephthalic acid to 2-aminoterephthalic acid, a linker containing amine functionalities in the synthesis media. The produced materials were characterized by different techniques, confirming the formation of the structure, their porosity and its functionalization. These results support that our simplified method to insert controllable amounts of amine functionalities on MIL-101(Cr) surface was employed successfully to produce materials that can present different surface character and reactivity.
