Charge-transporting polymer, composition for organic electroluminescent element, organic electroluminescent element, organic EL display, and organic EL lighting |
摘要 |
A subject for the invention is to provide a charge-transporting polymer having high hole-transporting ability and excellent solubility and film-forming properties and a composition for organic electroluminescent element which contains the charge-transporting polymer. Another subject for the invention is to provide an organic electroluminescent element which has a high current efficiency and high driving stability. The charge-transporting polymer comprises a group represented by the following formula (1) as a side chain: wherein in formula (1), the benzocyclobutene ring may have one or more substituents. The substituents may be bonded to each other to form a ring. The spacer represents a group which links the benzocyclobutene ring to the main chain of the charge-transporting polymer through three or more single bonds. |
