Detection And Separation

A novel supramolecular polymer material, OGV, based on long-alkyl-chained acylhydrazone was constructed. The OGV showed an ultrasensitive response for Hg2+ and Fe3+ in water by forming the metallogels HgG and FeG, which showed ultrasensitive detection and separation for CN− and H2PO4− in water, respectively.

We synthesize and develop 1,3-dihydro-2H-imidazo[4,5-b]phenazine-2-thione as a ratiometric chemosensor for recognition of Hg<sup>2+</sup> in DMSO/H<sub>2</sub>O (v/v = 9:1) binary solution. We rationally introduce the phenazine imidazole group as fluorophore and the thione moiety as recognition site to bind Hg<sup>2+</sup>. Interestingly, the chemosensor shows ultrasensitive response for Hg<sup>2+</sup> and the lowest limit of detection is 0.167 nM. In addition, it can also separate Hg<sup>2+</sup> from aqueous solution with excellent ingestion capacity, and the adsorption ratio is up to 96%. Furthermore, ion test strips based on the chemosensor are fabricated to conveniently and efficiently detect Hg<sup>2+</sup>.

We demonstrate a novel strategy to synthesize highly stable and luminescent mercaptoimidazole-capped copper nanoclusters (CuNCs). Simple modification of substituents on the mercaptoimidazole ligand dictates the self-assembly and photophysical properties of the clusters.
