    • The molecular dimensions (length, width, height, in Å) obtained from molecular mechanics calculations (PCMODEL, Ref. [42]) are: 18.1, 6.8, 3.5 (DCS) and 19.1, 6.8, 3.5 (ACS), taking into account the van der Waals radii of the atoms.

    • note
    • e(DCS) = 21 D finds support in the fact that the value (25 D) obtained for 4-dimethylamino-4′-nitrostilbene (DNS) by using the same electrochromic method (Ref. [3c]) is in good agreement with the more recent result (24 D) of time-resolved microwave conductivity experiments (Ref. [44]). Solvatochromic measurements with DNS suffer from the necessary spectral correction of its strongly red-shifted fluorescence spectra.
