The invention provides an organo-electronic functional material comprising a tris(arylamino)benzene represented by the general formula (I)
wherein A and B are each a group represented by the general formula (II)
in which R is an alkyl group of 1-6 carbons or a cycloalkyl group of 5 or 6 carbon atoms and n is 0, 1, 2 or 3, and A and B may be the same or different from each other, and exhibiting a cyclic voltamogram in which a deviation of peak current of cyclic curves as measured 50 times at a sweep rate of 20 mV/s falls within ±10% of the average of peak current.
The organo-electronic functional material has an opto-electronic exchanging function, a reversible oxidation-reduction property and a high glass transition temperature, and can form amorphous film in itself. In addition, it is stable and exhibits only slight variation of peak current in repeated oxidation-reduction process so that it is suitable for use as, for example, a hole transporting material among others in various electronic devices including an organic electroluminescence element.
本发明提供了一种有机电子功能材料,包括通式 (I) 所代表的三(芳基
氨基)苯
其中 A 和 B 分别为通式(II)所代表的基团
其中 R 是 1-6 个碳原子的烷基或 5 或 6 个碳原子的环烷基,n 是 0、1、2 或 3,A 和 B 可以相同或不同,并显示出循环伏安图,其中在 20 mV/s 的扫描速率下测量 50 次循环曲线的峰值电流偏差在峰值电流平均值的 ±10% 以内。
该有机电子功能材料具有光电交换功能、可逆氧化还原特性和较高的
玻璃化转变温度,本身可形成无定形薄膜。此外,它还很稳定,在反复的氧化还原过程中峰值电流变化很小,因此适合用作各种电子设备(包括有机电致发光元件)中的空穴传输材料等。
