Abstract
The precursor formamide 1 was employed instead of the monomer 2 because isocyanides are relatively unstable in air at room temperature. [19] a) [20] Molecular modeling shows that (in common with the phenyl benzo-ate compounds previously described [17]) an angle exists between the planar phenoxy and TTF ring systems. [21] The oxidation of the polymer was performed in a mixture of solvents to ensure solubility of reagents and products throughout the process. The CD spectra of the polymer in THF and in CH 2 Cl 2 are essentially identical, but the Cotton effects observed in CH 2 Cl 2 :MeCN 7:3 are somewhat different, presumably owing to aggregation, as seen in other polymeric systems. See a) B.1 mol of TTF unit, taking the molecular weight of the monomer. The Fe III salt was spectrophotometri-cally titrated as ferric acetate in water prior to use; see: D. [23] For references on calculated and experimental UV-vis absorption of cation radicals and dications of TTF derivatives, see: a) Silicon nanowires are attractive building blocks for nano-scale electronic systems due to their compatibility with existing semiconductor technology. Studies have focused on their synthesis, [1±5] with considerable advances made in the control of structures, [6] electrical, [7,8] and thermal [9] properties. For practical applications, different strategies have been explored to fabricate nanowire-based devices. The pick-and-place approach [7,8,9] has succeeded in making individual devices such
