Abstract

See full text

An object of the present invention is to provide a conjugated polymer which has a high hole transportability and is excellent in solubility and depositability. Another object of the present invention is to provide an organic electroluminescence element which is capable of low voltage driving and has a high luminous efficiency and drive stability. The conjugated polymer of the present invention is a conjugated polymer containing a specific structure as the repeating unit, where the conjugated polymer contains an insolubilizing group as a substituent, the weight average molecular weight (Mw) is 20,000 or more and the dispersity (Mw/Mn) is 2.40 or less.
