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.
该发明提供了一种有机电子功能材料,包括由通式(I)表示的三(芳基
氨基)苯,其中A和B分别是由通式(II)表示的基团,其中R是1-6碳原子的烷基基团或5或6碳原子的环烷基基团,n为0、1、2或3,A和B可以相同也可以不同,并且在循环伏安图中表现出峰电流的偏差,该偏差是在以20 mV/s扫描速率进行50次测量的循环曲线中,其峰电流的偏差在±10%内,与峰电流的平均值相匹配。该有机电子功能材料具有光电交换功能、可逆氧化还原性和高
玻璃化转变温度,并且可以自身形成非晶膜。此外,它稳定性高,在重复氧化还原过程中仅表现出轻微的峰电流变化,因此适用于用作各种电子设备中的孔传输材料,包括有机电致发光元件。
