Polymer, composition for organic electroluminescent element, organic electroluminescent element, organic EL display device, organic EL lighting, and manufacturing method for organic electroluminescent element
摘要
說明書
The alkyl groups represented by R15 and R16 are the same as the alkyl groups exemplified above for R1, R2, R3 and R6, and the aromatic hydrocarbon groups and the aromatic heterocyclic groups are the same as those exemplified above for Ar1 and Ar2. Further, substituent that may be contained in these groups are preferably the same as the above-described substituents Z and the below-described crosslinkable group, and substituents that may be further contained therein are the same as the above-described substituents Z.
[Other Repeating Unit (2)]
The other repeating unit that may be contained in the polymer of the present embodiment is preferably a repeating unit represented by the following Formula (7). The repeating unit represented by Formula (7) tends to have a high excited singlet energy level and a high excited triplet energy level because of distortion of the aromatic rings. In addition, steric hindrance caused by the distortion of the aromatic rings allows the polymer to have excellent solubility in solvents, and a coating film thereof formed by a wet film-forming method and subsequently heat-treated tends to have excellent insolubility in solvents.
(wherein,
Ar5 represents an aromatic hydrocarbon group optionally having a substituent, or an aromatic heterocyclic group optionally having a substituent;
