A charge-transporting organic material containing a compound with a 1,4-dithiin ring, which is represented by the following formula (1), is described.
When using a thin film made of such an organic material in a low-molecular-weight organic EL (OLED) element and a polymer organic EL (PLED) element, EL element characteristics such as low drive voltage and high luminous efficiency can be improved. In addition, a charge-transporting varnish containing the compound with a 1,4-dithiin ring represented by the above formula (1) has good processing properties, and a thin film obtained therefrom has high charge-transporting characteristics and thus is effective for application to protective films for capacitor electrodes, antistatic films, solar cells or fuel cells.
本文描述了一种电荷传输有机材料,它含有一个 1,4-二硫杂环化合物,由下式(1)表示。
在低分子量有机电致发光(OLED)元件和聚合物有机电致发光(PLED)元件中使用由这种有机材料制成的薄膜时,可以提高电致发光元件的特性,例如低驱动电压和高发光效率。此外,含有由上式(1)表示的具有 1,4-二硫环的化合物的电荷传输清漆具有良好的加工性能,由此获得的薄膜具有高电荷传输特性,因此可有效地应用于电容器电极保护膜、抗静电膜、太阳能电池或燃料电池。
