Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a polymer for an organic electroluminescent element capable of coating without dissolving an under layer when forming an organic compound layer and suppressing increase of a drive voltage of the organic electroluminescent element.SOLUTION: The polymer used for forming an organic electroluminescent element having a structure in which a plurality of layers are laminated between a negative electrode and a positive electrode formed on a substrate includes a main chain skeleton having a conjugate system structure and a polyalkyleneimine structure whose degree of polymerization is equal to or more than 3. The polyalkyleneimine structure is bonded with the main chain skeleton having the conjugate system structure directly and/or through a coupling group.
【課題】有機化合物層を形成する際に下層を溶解することなく塗布が可能であり、かつ、有機電界発光素子の駆動電圧の上昇を抑えることが可能な有機電界発光素子用重合体を提供する。【解決手段】陰極と、基板上に形成された陽極との間に複数の層が積層された構造を有する有機電界発光素子の形成に用いられる重合体であって、該重合体は、共役系構造を有する主鎖骨格と、重合度が3以上のポリアルキレンイミン構造とを含み、該ポリアルキレンイミン構造は、該共役系構造を有する主鎖骨格と直接および/または連結基を介して結合している、有機電界発光素子用重合体である。【選択図】図2 |
