<p>An organo-electronic functional material characterized in that it comprises a tris(arylamino)benzene of the general formula: (I) (wherein A and B are groups of the general formula: (II) (in which R is a C1-C6 alkyl or a C5 or C6 cycloalkyl; and n is 0, 1, 2 or 3), which groups may be identical with or different from each other), and that in a cyclic voltagram, the organo-electronic functional material exhibits a deviation of peak current of 50-cyclic curve, measured at a sweep rate of 20 mV/s, falling within ±10% of the average of peak current. This organo- electronic functional material has photo-electron conversion capability, being reversible in oxidation-reduction and by itself can form an amorphous film. Further, not only is the glass transition temperature thereof high but also even in repeated oxidation-reduction, the change of peak current value is slight, ensuring stability. Therefore, the organo- electronic functional material can be appropriately used as, for example, a hole transport material in various electronic devices including organic electroluminescence devices.</p> |
