量子点发光层及其制备方法和应用
摘要：
本发明公开了一种量子点发光层及其制备方法和应用。本发明量子点发光层包括量子点，所述量子点结合有有机配体，所述有机配体为X1-R1-C≡C-C≡C-R2、X2-M-R3、X3-R4-CH2-CH2-R5中的至少一种，所述X1、X2和X3与量子点表面结合，且至少在所述量子点发光层表层的所述有机配体通过所含的-C≡C-C≡C-、-M-或-CH2-CH2-中的至少一种基团交联；其中，所述X1、X2和X3为与量子点表面结合的基团，所述R1、R2、R3、R4、R5独立选自具有共轭或非共轭基团的烃基或烃基衍生物，M为芳基。本发明量子点发光层结构质量稳定和发光性能稳定。
摘要（英）：

The invention discloses a quantum dot light emitting layer and a preparation method and an application thereof. The quantum dot light emitting layer includes quantum dots, and the quantum dots are combined with organic ligands. The organic ligands include at least one of X1-R1-C-triple-bond-C-C-triple-bond-C-R2, X2-M-R3 and X3-R4-CH2-CH2-R5, the X1, X2 and X3 are bound to the surface of the quantum dots, and at least the organic ligands on the surface of the quantum dot light emitting layer are cross-linked by at least one of the groups - C-triple-bond-C-C-triple-bond-C-,-M- and -CH2-CH2- contained in the organic ligands, wherein the X1, X2 and X3 are groups bound to the surface of the quantum dots, the R1, R2, R3, R4 and R5 are independently selected from alkyl or alkyl derivative with conjugated or non-conjugated groups, and M is aryl. The quantum dot light emitting layer of the invention has stable structure quality and stable light emitting performance.
