Notes:
New types of complex salts of 7,7′,8,8′-tetracyanoquinodimethane with aromatic ionenes and their model compounds were prepared. The electrical conductivity and the activation energy were measured and discussed in relation to their structure. The effects of the nature of the aromatic unit, and the flexibility and rigidity of the polymer backbone were compared with the corresponding model compounds. The effects of frequency and temperature are discussed in terms of the molecular strucuture of the complex. The electroconductivity at room temperature of the 1 : 1 polymer complex salts was found to be between 2 × 10-4 and 7 × 10-5S/cm, while that of the model complex salts was between 1.3 × 10-3 and 6.3 × 10-3S/cm. The activation energy was found to be 0.14 eV on average. The limitation of the concept of polycationic complex salts of TCNQ for electrically conductive plastics for commerical application in the plastics industry is discussed.
