“…650 nm tailing to near-infrared region. This band is characteristic for viologen radical monocations [77,78] and it is worth noting here that no clear signs of -dimer bands, expected around 550 nm and above 800 nm, are seen [79][80][81] indicating that either 1a(PF 6 differ by two electrons, the pattern of their electron transitions should be similar, which is indeed the case. Apparent differences in shape and spectral band positions manifest charge transfer character of 1a responding to different ionic environment this molecule is generated in.…”

“…The prototype ECDs are generally fabricated using optically-transparent electrodes, in a "sandwich" 12 or lateral 13 configurations, and consist of two electrodes (in which at least one is composed of an EC material), separated or covered by a layer of electrolyte. 6 With the application of an appropriate electrical potential, the colour change occurs as a result of the charge / discharge of the cell. 14,15 Among the several known EC materials (e.g.…”

We report the application of two poly [Ni(salen) was used to fabricate a solid state electrochromic device using lateral configuration with two figures of merit: a simple shape (typology 1) and a butterfly shape (typology 2); typology 1 showed the best performance with optical contrast ∆T = 88.7 % (at λ = 750 nm), colouration efficiency η = 130.4 cm 2 C -1 and charge loss of 37.0 % upon 3000 redox cycles.]

“…For absorptive/transmissive ECDs, the secondary electrode system is chosen to be a redox reaction where there is imperceptible visible colour change or as an electrochromic material where the change in colour is complementary [3] or reinforcing [4] to that at the primary electrode.…”

• AbstractPrototype electrochromic devices (ECDs) based on anodically-colouring thin-film Prussian blue (PB) or Ruthenium purple (RP) and cathodically-colouring aqueous solution-phase di-n-heptyl viologen are described. The initial ('off') state of each ECD is set with the PB (or RP) in the colourless reduced form and the di-n-heptyl viologen as the colourless di-cation. Switching the ECDs to the coloured state ('on'), forms on oxidation the coloured mixed-valence PB (or RP), with simultaneous reduction of the di-n-heptyl viologen di-cation to form the purplish-red di-n-heptyl viologen radical cation dimer salt as a thin film. The overall perceived reversible colour changes were colourless to deep blue/purple for the PB/di-n-heptyl viologen ECDs and colourless to pinkish-purple for the RP/di-n-heptyl viologen ECDs. Using the Commission Internationale de l'Eclairage (CIE) system of colorimetry, the colour stimuli of the ECDs were calculated from in situ visible region spectra recorded under electrochemical control, the depth of colour being controlled by the di-n-heptyl viologen concentration. For the coloured states of the PB/di-n-heptyl viologen di-n-heptyl viologen solution concentrations. L* quantifies the lightness, with +a*, -a*, +b* andb* respectively giving the red, green, yellow and blue directions away from the achromatic point (0, 0).-2 -
