  • Patent number: 7271291
    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.
    Type: Grant

  • Patent number: 7196224
    Abstract: The invention provides 1,3,5-tris(arylamino)benzenes represented by the general formula (I) wherein A is naphthyl, anthryl, phenanthryl, biphenylyl or terphenylyl group, and R is alkyl having 1–6 carbon atoms or cycloalkyl group having five or six carbon atoms. The 1,3,5-tris(arylamino)benzenes have oxidation potentials in the range of about 0.5–0.6V, excellent reversibility in oxidation-reduction process and high glass transition temperatures and 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.
