High electrochemical stability of meso-Ni-salen based conducting polymer manifested by potential-driven reversible changes in viscoelastic and nanomechanical properties

Electrocatalytic Properties of Ni(II) Schiff Base Complex Polymer Films

“…The relative ease of obtaining such electrodes allows their use as sensors, e.g., dipyrone [ 13 ], barium ions [ 14 ], nitric oxide [ 15 ] and BrO 3 − , IO 3 − , IO 4 − anions [ 16 ], furosemide [ 17 ] and oxygen [ 18 ]. They also play the role of potential materials in energy storage devices [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”

Nickel Salicylideniminato 1D MOFs via Electrochemical Polymerization

“…An observed consistent increase in the mass and oxidation/reduction current in 0.0–0.5 V potential range are typical indications of polymer deposition process (Figure 7a). CV curve of the resulting polymer in monomer free electrolyte solution has the complex multi‐peak shape which is typical for conductive polymers [18,33,51–55] . The sharp increase in mass at first cycles corresponds to the inbound flux of charge‐compensating ions accompanied by an irreversible polymer swelling, which added 5 μg cm −2 to the 24.7 μg cm −2 mass of the dry film (Figure 7b).…”

Getting closer to the intrinsic properties of Ni2+salen polymer semiconductors accessed by chain isolation inside silica nanochannels

“…Poly(meso-NiSaldMe-3dMe) based molecular wires and continuous film were prepared in a three-electrode cell configuration by electropolymerization under potentiodynamic conditions from the propylene carbonate solution containing 0.5 mM monomer and 0.1 M (TBA)PF 6 in the potential range of 0.0 to 1.7 V vs. Ag/Ag + at 100 mV s À1 . The propylene carbonate solution of 0.1 M (TBA)PF 6 was selected as an electropolymerization medium as it enables formation of Ni 2+ salen polymers with high operational stability upon doping and dedoping cycling, 42,44,45 contrary to, e.g. (TBA)ClO 4 in acetonitrile, for which entrapment of perchlorate anions may lead to poorer long-term stability.…”
