摘要

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.

主权项

1. A conjugated polymer comprising a repeating unit represented by the following formula (I), wherein
said conjugated polymer has a weight average molecular weight (Mw) of 20,000 or more and a dispersity (Mw/Mn, here Mn indicates a number average molecular weight) of 2.40 or less:wherein m represents an integer of 0 to 3,
each of Ar11 and Ar12 independently represents a direct bond, an aromatic hydrocarbon group which may have a substituent, or an aromatic heterocyclic group which may have a substituent, and each of Ar13 to Ar15 independently represents an aromatic hydrocarbon group which may have a substituent, or an aromatic heterocyclic group which may have a substituent, provided that both Ar11 and Ar12 do not represent a direct bond, and said conjugated polymer comprises an insolubilizing group as a substituent and which is at least one of a cycloether group, a vinyl ether group, or an arylvinylcarbonyl group.
