摘要

PROBLEM TO BE SOLVED: To provide a conjugated polymer showing a high hole transport capacity and excellent solubility and film forming properties, and an organic electroluminescent element capable of activation at low power voltage and with high electroluminescent efficacy and driving stability.SOLUTION: A conjugated polymer includes a specific structure as a repetitive unit, and has a specific crosslinkable group as a substituent. In the conjugated polymer, the weight average molecular weight (Mw) is 20,000 or more, and the dispersion degree (Mw/Mn) is 2.40 or less.
