Biscyanimine of the general formula in the R¹ for 1- or 2-propyl, for C₅- to C₂₀-alkyl, C₃- to C₂₀-alkenyl or iodine and R², R³ and R⁴ independently represent hydrogen, chlorine, bromine, iodine, fluorine, phenyl, C₁- to C₂₀-alkyl, C₃- to C₂₀-alkenyl or C₁- to C₈-alkoxy.n n n The biscyanimines (I) give fulvalene compounds of the formula the ratio of (I): (II) = 1: 1, 2: 1, 3: 2, 1: 2 or 2: 3 mol is charge transfer complexes which are electrically conductive.n n n The biscyanimines (I) also give electrically conductive radical ion salts of the formula in the R¹, R² and R⁴ have the meaning given above and M m⊕ for an m-valent alkali metal, alkaline earth metal, transition metal, ammonium or phosphonium ion, k for 1 to 3, l for 1 to 3, m for 1 or 2, n for 1 to 3 and z stands for 0 to 2, where k, l, n and z can also be fractional numbers and the sum (l + z) = n · m.n n n The charge transfer complexes which can be prepared from (I) and the radical ion salts (III) are suitable, for example for electrical semiconductors and photoconductors, as electrode and storage material in electrical batteries, for fuel cells and for the antistatic finishing of plastics. |
