Pillararenes, a rising star in macrocyclic chemistry, are recognized as promising organic materials for metal ion separation. Herein, three novel pillar[5]arenes (1a-c) appended with N,N-dimethyldithiocarbamoyl groups were designed for highly efficient extraction of aqueous mercury. This work represents the first case of using pillararene- based materials for organic mercury removal, and rather low Hg(II) residue (3.45 ppb) was found in the extraction raffinate of mercury spiked river water after being treated with the as-prepared extractants, which is a rare example of solvent............
