| 发明名称 | Arylsulfonic acid compound and use thereof as electron-acceptor material | ||
| 摘要 | Disclosed is an arylsulfonic acid compound characterized by being represented by formula (1). By using this compound as an electron-acceptor material, highly uniform film formability can be achieved. By using a thin film containing the arylsulfonic acid compound in an OLED device or a PLED device, there can be obtained excellent EL device characteristics such as low driving voltage, high luminous efficiency and long life.; (In the formula, X represents O, S or NH; Ar represents an aryl group; and n represents the number of sulfonic groups, which is an integer of 1-4.). | ||
