Preferred Definitions:    R1-R19=H.    EXAMPLE - 4-hydroxy diphenylamine (in g) (50.36), 4-amino-diphenylamine (50.04) and spin dried toluene 550 ml were heated to 90degrees C. Titanium catalyst was dissolved in toluene (200 ml) and added to the reaction liquid, and heated to 100degrees C. The reaction liquid was cooled to room temperature and obtained crystals were filtered and dried to obtain phenyl trianiline (85.44) with yield of 90%. The obtained trianiline (20) was dissolved in tetrahydrofuran (400 ml) and silver oxide (26.38) was added, and stirred. Cerite filtration of the reaction liquid was carried out and oxidized phenyl trianiline was obtained. The oxidized compound (100 mg), 5-sulfo salicylic acid dihydrate (218 mg) and dimethyl acetamide (1.79 ml) were stirred at room temperature. Cyclohexanol (5.31 ml) was added and the mixture was heated to 50degrees C and stirred to obtain green black transparent solution. The solution was filtered to obtain charge transportable varnish. The varnish was used for forming uniform non-crystalline charge transportable thin film. The organic electroluminescent element using the formed film had high luminous efficiency.
