Popis: | A 2D anionic Cd-based coordination host was constructed from the linkage of the metal ions and 6-sulfonicotinic acid (SNA, in situ generated from the breaking of disulfide bond in 6,6’-dithiodinicotinic acid) whose interior spaces are occupied with cationic [(CH3)2NH2]+ guests. The compound exhibits an interesting ion-exchange behavior for both encapsulation of lanthanide (Ln) ions and organic dye. Through the fixation of Ln3+ within the host, the designed composite can be endowed with high photoluminescence property. Moreover, the free cations could be readily substituted by methylene blue (MB), with more than 90% of MB (10−5 M) being selectively absorbed after 12 h, making the title compound to be a great medium for dye adsorption and separation. |
