ABSTRACT:
The invention provides 1,3,5-tris(arylamino)benzenes represented by the general formula (I)wherein A is naphthyl, anthryl or phenanthryl group, and R is hydrogen atom or diarylamino group.These 1,3,5-tris(arylamino)benzenes have oxidation potentials in the range of about 0.5-0.6V, excellent reversibility in oxidation-reduction process, high glass transition temperatures and high heat resistance, so that they can form practicable organic semiconductor film readily by a coating method or a vacuum deposition method. In addition, they are capable of forming stable and durable amorphous film useful as high performance organic semiconductors at normal temperatures or higher with no aid of binder resins, that is, by themselves.
