Cu(I)-organic Framework As a Platform for High-Efficiency Selective Adsorption of Methylene Blue and Reversible Iodine Uptake

A Cu(I)-MOF, namely {[Cu(4-RTZ)]center dot(H2O)(0.5)}(n). (1), that contains rhombic channels with the size of 10.174 angstrom x 16.965 angstrom has been obtained based on in situ generated 5-(4-pyridyl)-1H-tetrazole ligand. Compound 1 not only displays remarkable capability for selective adsorption toward the organic dye Methylene Blue (149.5 mg g(-1)), but also shows reversible adsorption of 1 2 molecules in hexane medium (96.2%). Therefore, compound 1 should be a promising MOF-based bifunctional adsorbent in the field of pollutant removal.
