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.
本发明提供了由通式(I)表示的1,3,5-三(芳基氨基)苯,其中A为萘基,蒽基或菲基基团,R为氢原子或二芳基氨基基团。这些1,3,5-三(芳基氨基)苯具有约0.5-0.6V的氧化电位,在氧化还原过程中具有优异的可逆性,高玻璃化转变温度和高耐热性,因此它们可以通过涂覆法或真空沉积法轻易地形成实用的有机半导体薄膜。此外,它们能够在常温或更高温度下自行形成稳定耐用的非晶态薄膜,用作高性能有机半导体,无需使用粘合剂树脂。
