Title: Innovations of Tomoko Hayashi
Introduction
Tomoko Hayashi is a prominent inventor based in Kobe, Japan. She has made significant contributions to the field of organic semiconductors, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
Her latest patents include the invention of 1,3,5-tris(arylamino)benzenes. This invention provides compounds represented by the general formula (I), wherein A is a naphthyl, anthryl, or phenanthryl group, and R is a hydrogen atom or diarylamino group. These compounds exhibit oxidation potentials in the range of about 0.5-0.6V, excellent reversibility in the oxidation-reduction process, high glass transition temperatures, and high heat resistance. They can form practical organic semiconductor films readily through coating or vacuum deposition methods. Additionally, they can create stable and durable amorphous films that are useful as high-performance organic semiconductors at normal temperatures or higher without the need for binder resins.
Another patent also focuses on 1,3,5-tris(arylamino)benzenes, represented by a similar general formula (I), where A can be a naphthyl, anthryl, phenanthryl, biphenylyl, or terphenylyl group, and R is an alkyl group with 1–6 carbon atoms or a cycloalkyl group with five or six carbon atoms. These compounds share similar properties, including oxidation potentials in the range of about 0.5–0.6V and the ability to form stable and durable amorphous films for high-performance organic semiconductors.
