| titleOfInvention | Quantum dot light-emitting layer and preparation method and application thereof |
| abstract | The invention discloses a quantum dot light-emitting layer and a preparation method and application thereof. The quantum dot light-emitting layer comprises quantum dots, wherein the quantum dots are combined with an organic ligand, and the organic ligand is X 1 ‑R 1 ‑C≡C‑C≡C‑R 2 、X 2 ‑M‑R 3 、X 3 ‑R 4 ‑CH 2 ‑CH 2 ‑R 5 At least one of (A), the X 1 、X 2 And X 3 The organic ligand is combined with the surface of the quantum dot, and at least on the surface layer of the luminescent layer of the quantum dot is composed of-C-, -M-or-CH 2 ‑CH 2 -at least one group of (a); wherein, X is 1 、X 2 And X 3 Is a group combined with the surface of the quantum dot, and R is 1 、R 2 、R 3 、R 4 、R 5 Independently selected from hydrocarbyl or hydrocarbyl derivatives having conjugated or non-conjugated groups, and M is an aryl group. The quantum dot light-emitting layer has stable structural quality and stable light-emitting performance. |
