Novel triarylamine polymer, process for producing the same, and use thereof

摘要

It is an object of the present invention to provide a novel triarylamine polymer which is excellent in solubility and film-forming property and has improved thermal stability; a simple process for its production; and an electronic element employing it. A triarylamine polymer represented by the following formula (1) (wherein each of Ar¹, Ar², Ar³, Ar⁴, Ar⁵, Ar⁶ and Ar⁷ which are independent of one another, is an unsubstituted or substituted C_6-60 aromatic group, Ar¹ and Ar² are the same or different, Ar³ and Ar⁴ are the same or different, and m is an integer of at least 1), a process for its production, and an electronic element employing it, are provided:
