AI Article Synopsis

  • The researchers created Ni(II) and Al(III) 10-azacorroles by using nitrogen-bridged bisdipyrrins in a coordination-induced cyclization process.
  • Al(III) 10-azacorrole showed different optoelectronic properties compared to Ni(II) 10-azacorrole.
  • This difference highlights how the azacorrole ligand affects electronic behavior differently than porphyrin does.

Article Abstract

We have synthesized Ni(II) and Al(III) 10-azacorroles through coordination-induced cyclisation of nitrogen-bridged bisdipyrrins. Al(III) 10-azacorrole displayed contrasting optoelectronic behaviours from Ni(II) 10-azacorrole, underlining the different electronic effects of the azacorrole ligand from the porphyrin.

This study is the first application of a PVDF-HFP-based polymer inclusion membrane incorporating the poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and di(2-ethylhexyl)phosphoric acid (D2EHPA) as the base polymer and extractant for the extraction of bismuth(III), respectively. It is demonstrated that the PIM comprised of 60 wt% PVDF-HFP and 40 wt% D2EHPA is the most effective in the extraction of bismuth(III) from feed solution containing 20 mg L bismuth(III) and 0.2 mol L sulfate adjusted to pH 1.

Extraction ability of N,N-dioctylthiodiglycolamic acid (T-DODGAA), a soft-base sulfur donor ligand with an amide group and a carboxylic acid connected by a thioether chain, for 56 metal ions have been comprehensively investigated and compared with that of N,N-dioctyldiglycolamic acid (DODGAA) with an etheric oxygen atom, a hard-base donor. The acid dissociation constant (pK) of the thiodiglycolamic acid framework was determined to be 3.71 ± 0.

Phage display technology employs a library of engineered filamentous M13 viruses infecting only bacteria. In this study, the genuine phage display selection technique was applied to identify a Pb(II) specific peptide. After three rounds of positive selection against Pb(II) coated agarose-based beads and the consecutive negative screenings against interfering metal ions (Al(III), Co(II), Fe(III), Ni(II), and Zn(II)), a final phage library with enhanced Pb(II) binding was obtained.

A simple, rapid, sensitive and inexpensive approach is described in this work based on a combination of solid-phase extraction of 8-hydroxyquinoline (8HQ), for speciation and preconcentration of Cr(III) and Cr(VI) in river water, and the direct determination of these species using a flow injection system with chemiluminescence detection (FI-CL) and a 4-diethylamino phenyl hydrazine (DEAPH)-hydrogen peroxide system. At different pH, the two forms of chromium [Cr(III) and Cr(VI)] have different exchange capacities for 8HQ, therefore two columns were constructed; the pH of column 1 was adjusted to pH 3 for retaining Cr(III) and column 2 was adjusted to pH 1 for retaining of Cr(VI). The sorbed Cr(III) and Cr(VI) species were eluted from columns using 3.

A series of quaternary Np(IV) fluorides was synthesized using a mild hydrothermal synthesis approach. The compositions are all of the type NaMNpF, where M = Ti(III), V(III), Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Al(III), and Ga(III) and = 4 for divalent metals, = 3 for trivalent metals. The compounds all crystallize in the -31 space group and are isotypic with actinide analogues NaMAnF (An = Ce, U, Th, Pu).
