The invention provides an organo-electronic functional material comprising
a tris(arylamino)benzene represented by the general formula (I)
##STR00001## wherein A and B are each a group represented by the general
formula (II) ##STR00002## in which R is an alkyl group of 1-6 carbons or
a cycloalkyl group of 5 or 6 carbon atoms and n is 0, 1, 2 or 3, and A
and B may be the same or different from each other, and exhibiting a
cyclic voltamogram in which a deviation of peak current of cyclic curves
as measured 50 times at a sweep rate of 20 mV/s falls within .+-.10% of
the average of peak current.The organo-electronic functional material has
an opto-electronic exchanging function, a reversible oxidation-reduction
property and a high glass transition temperature, and can form amorphous
film in itself. In addition, it is stable and exhibits only slight
variation of peak current in repeated oxidation-reduction process so that
it is suitable for use as, for example, a hole transporting material
among others in various electronic devices including an organic
electroluminescence element.
