Fabrication of metal organic frameworks with amino group and corresponding properties

ABSTRACT

A series of metal organic frameworks with amino group and excellent hydrostability were designed and fabricated by means of regulating organic ligands, which were characterized and used to enrich oleuropein from aqueous solution. The results showed that the specific surface area and pore structure could be modulated and overmuch amino group would be unfavorable for the adsorption efficiency for oleuropein. Hydrogen bonding, sieving effect hydrophobic interaction, and π-π were involved in the adsorption process. The excellent adsorption efficiency and regeneration make the present materials highly promising useful in practical application to enrich oleuropein from aqueous solution.
