An oligoaniline compound represented by the formula (1) can provide a charge transporting thin film which shows a suppressed coloration in the visible range. Use of this thin film makes it possible to ensure a color reproducibility of a device without lowering the color purity of an electroluminescent light or a light having passed through a color filter.
wherein R1 to R10 independently represent each a hydrogen atom, a halogen, etc.; m and n independently represent each an integer of 1 or more while satisfying the condition m+n ≤ 20; and X is a structure represented by any of the following formulae (4) to (10), etc.;
wherein R21 to R36 independently represent each a hydrogen atom, a hydroxyl group, etc.; p and q represent each an integer of 1 or more while satisfying the conditions p ≤ 20 and q ≤ 20; and W1s independently represent each -(CR1R2)p-, -O-, -S-, etc.
由式(1)表示的低聚苯胺化合物可以提供一种电荷传输薄膜,它在可见光范围内显示出抑制的色度。使用这种薄膜可以确保设备的色彩再现性,而不会降低电致发光或通过彩色滤光片的光的色彩纯度。
其中 R1 至 R10 各自独立地代表氢原子、卤素等;m 和 n 各自独立地代表 1 或更大的整数,同时满足 m+n ≤ 20 的条件;以及 X 是由下式(4)至(10)中的任一式所代表的结构等;
其中 R21 至 R36 各自独立地代表氢原子、羟基等;p 和 q 各自代表 1 个或 1 个以上的整数,同时满足 p≤20 和 q≤20 的条件;W1s 各自独立地代表-(CR1R2)p-、-O-、-S-等。
