Any of the oligoaniline compounds with a triphenylamine structure represented by the formula (1) exhibits satisfactory light emitting efficiency and brightness performance when used in either an OLED device or a PLED device and is further satisfactory in the solubility in organic solvents so as to be applicable to various coating methods. (each of R1 and R2 independently is a hydrogen atom, an optionally substituted monovalent hydrocarbon group, t-butoxycarbonyl, etc.; each of R3 to R34 independently is a hydrogen atom, hydroxyl, silanol, thiol, carboxyl, a phosphoric group, a phosphoric ester group, ester, thioester, amido, nitro, an optionally substituted monovalent hydrocarbon group, etc.; and each of m and n is an integer of 1 or greater provided that they satisfy the relationship m+n≦̸20). |
