Abstract: Three triphenyldiamine derivatives(TPDs) were synthesized by Ullmann reaction of N,N'-diphenyl benzidine with p-CH3, p-OCH3, m-CH3 iodobenzenes, respectively, using 18C6 as phase transfer catalyst and o dichlorobenzene as solvent. Their structures have been verified by IR and NMR maesurements. As a charge transfer agent, addition of TPD improves the luminescent property of the electroluminescent devices.

Key words: substituted triphenyldiamine, synthesis, Ullmann reaction, electroluminescent property
