Structural diversity in mercury(II) coordination complexes with asymmetrical hydrazone-based ligands derived from pyridine

Development of Hg2+ sensor based on N′-[1-(pyridin-2-yl)ethylidene]benzenesulfono-hydrazide (PEBSH) fabricated silver electrode for environmental remediation

“…Further increase of Hg 2+ ions concentration on PEBSH/AgE surface, it is exhibited a more rapid increased the current responses, due to larger area covered by Hg 2+ ions and the p-p interaction of the functional groups (lone pairs of nitrogen). The p-p interaction could be approaches as per the schematic view, inter-molecular Scheme 2(b) and intramolecular Scheme 2(c) interaction of the sulphonyl hydrazones as per explained by Masoumi et al 54 Usually, the surface coverage of Hg 2+ ions on PEBSH//binders/AgE surface is reached to saturation, based on the regular enhancement of current responses. To support the binding of Hg 2+ with sensor PEBSH, FTIR studies were carried out, as per request.…”

Preparation of polyaniline grafted graphene oxide–WO3 nanocomposite and its application as a chromium(iii) chemi-sensor

“…The p-p interactions could be approached as per the schematic view (Scheme Pa †), or intermolecular and intramolecular (Scheme Pb †) interactions of the electron rich system as explained in the published works. 67,68 Usually, the surface coverage of Cr 3+ ions on the PANI-g-rGO@WO 3 /binder/ AgE surface reaches saturation, based on the regular enhancement of the current responses.…”

Hybrid poly(ether-arylidene-ether-sulphone)s derivatives for divalent cobalt ion detection

“…This attributed to larger area is covered by Co +2 ions and the π-π interaction of the functional groups in copolymer 8 e . The π-π and π-π* interaction could be approached as inter-molecular and intra-molecular interactions of the copolymer 8 e [56]. Usually, the surface coverage of Co +2 ions on copolymer 8 e /binder/GCE surface was reached to saturation, based on the regular enhancement of current responses.…”
