Any oligoaniline compound with triphenylamine structure shown in formula (1) shows satisfactory luminous efficiency and brightness performance when used in OLED devices or PLED devices, and the solubility in organic solvents Satisfactory as to be applicable to various coating methods. (R 1 and R 2 are each independently a hydrogen atom, an optionally substituted monovalent hydrocarbon group, tert-butoxycarbonyl, etc.; R 3 to R 34 are each independently a hydrogen atom, a hydroxyl group, a silanol group, a thiol group, a carboxyl group , phosphate group, phosphate ester group, ester group, thioester group, amido group, nitro group, optionally substituted monovalent hydrocarbon group, etc.; m and n are each an integer greater than or equal to 1, provided that they satisfy m+n≤ 20 relationship). |
