| Abstract |
Metal-organic frameworks (MOFs), constructing via coordination bond between inorganic secondary building units (SBU) and organic building block, have emerged as the innovative porous materials. Enormous surface areas, versatile tenability, confined pore-size and regularity of MOFs enable us to demonstrate the various applications including gas storage, separation, sensing, drug delivery, electrocatalysis and catalysis. In addition, MOFs have been employed in adsorbent materials for sequestration of metal ions from the aqueous solutions. Diverse heavy and transition metals have been effectively captured by various MOFs. Strong adsorption site or ion exchange sites in the confined pore size of MOFs play a pivotal role in selective sequestration of specific metal ions from the solution.
In this study, we used Zr-based MOF, NU-1000 for capturing mercury ion. Incorporation of the strong binding site such as thiol group via solvent-assisted ligand incorporation (SALI) plays a key role to sequestrate mercury ions. Moreover, the modified MOF exhibited fluorescence quenching phenomenon under UV confirming the mercury detection ability.
