Dependence on the Substituents of the Photoconduction from ArylaminesAromatic amines are often used as charge transporting agents in electrophotographic two-layer-systems. Structure-property-relations of this substance class are discussed on the basis of homogeneously sensitized polycarbonat-layers containing derivatives of anilines. Substituent variation of the actinic compounds has a significant influence on the electrophotographic sensitivity. Correlations between Hammett substituents constants and electrophotographic sensitivity are useful for the preselection of arylamin structures. Dibenzylamino groups lie out of these correlations and induce an unexpected high photoconductivity. This fact was investigated by cyclovoltammetric measurements of 22 various dibenzylanilines. Low half-peakpotentials and reversible one-electron oxidation steps of dibenzylanilines are necessary for outstanding photoconductor properties.
