The present invention relates to 1, 3, 5-tris (arylamino) benzenes of the general formula (I).n n n Since the compound has an oxidation potential of about 0.5 to 0.6 V, excellent reversibility in the redox process, high glass transition temperature, and excellent heat resistance, the compound has excellent practicality by coating and vacuum deposition. Since the film can be easily produced and, in addition, a stable amorphous film can be formed on its own at a temperature higher than room temperature, that is, without the help of a binder resin, a stable and durable high performance organic semiconductor film made of itself can be formed.n n n Formula In n n n n n n n In said formula, A represents a naphthyl group, anthryl group, or a phenanthryl group, and R represents a hydrogen atom or a diarylamino group. |
