Correlating structure and ion recognition properties of [Ni(salen)]-based polymer films

Electrocatalytic Oxidation of 1-Propanol and 2-Propanol on Electro-active Films Derived from NiII-(N,N′-bis(2-Hydroxy, 3-Methoxy Benzaldehyde)-1,2-Propandiimine) Modified Glassy Carbon Electrode

“…In the following cycles, the current intensity associated with both the anodic and the cathodic peaks increases, indicating progressive accumulation of the electro-active film on the electrode surface. The voltammetric responses as well as their evolution during the polymerization process are qualitatively similar to those observed for analogous Ni-and Cu-salen complexes [33][34][35] although the peaks assigned to the deposited film are detected at much less positive potentials. The current rise following the anodic scan wave is the result of the oxygen evolution reaction.…”

High-Performance Electrochromic Devices Based on Poly[Ni(salen)]-Type Polymer Films

“…In general, the voltammetric responses of polymeric films stabilised after 5 scans, which correspond to the typical "film conditioning". 43,45 The coulometric data revealed Γ = 0.31 and 1.13 µmol cm -2 for poly [1] and poly [2], respectively, suggesting greater polymerization efficiency for poly [2].…”

“…the reduction of film deposited in the preceding anodic scan. 43,44 In the second and subsequent voltammetric cycles (5 th cycle in Table S1), a new peak appears at Epa ≈ 0.42 V for the [Ni(3-Mesalen)] system which is assigned to polymer film oxidation deposited during the previous cycle(s); 43,44 in the reverse cathodic, the peaks at Epc = 0.64 and 0.22 V are due to the oligomers and polymer film reductions. In the case of [Ni(3-MesaltMe)], two new peaks appear during the second and subsequent scans (5 th cycle in Table S1) The voltammetric responses of the as-prepared poly [1] and poly [2] films in the electrolyte solutions LiClO4/CH3CN and LiClO4/PC 0.1 mol dm -3 are depicted in Figure 2 and, in Table S2, are summarized the potential peak values.…”

Preparation and characterization of poly[Ni(salen)(crown receptor)]/multi-walled carbon nanotube composite films

“…The aim is to enhance the intrinsic characteristics of poly[Ni(salen)] films by the insertion of MWNTs into the polymeric matrix. We have previously studied the polymer component by a range of acoustic wave electrogravimetric [28] and structural techniques [29,30] leading to the establishment of correlations between structure and reactivity. The structural information is relevant to the understanding and optimization of Ba 2+ ion recognition and uptake by poly[Ni(salen)(crown)] films, where the selectively pre-concentrated metal ion can be determined gravimetrically on the nanomole scale.…”
