Paragraph 0084-0090, (2021/05/12)
The invention discloses a quantum dot ligand, a quantum dot, an electroluminescent device and a preparation method thereof, and a display device. The structural general formula of the quantum dot ligand is R1-M-R2, wherein M is used for providing at least two connecting sites, R1 is a hydrophilic group, and R2 is used for forming coordinate bonds with the surfaces of the quantum dots. The quantum dot ligand provided by the invention at least contains a hydrophilic group, so that the hydrophilicity of a quantum dot light-emitting layer can be improved. When an electron transport layer is prepared on the quantum dot light-emitting layer, the spreadability of electron transport layer ink on the quantum dot light-emitting layer can be improved, and the defect of exciton quenching caused by permeation of electron transport layer particles into the gaps of the quantum dot light-emitting layer can be overcome, so that the performance of the device can be greatly improved.

A carbazole-based gold(I) complex 1 has been successfully synthesized. Its structure was characterized by nuclear magnetic resonance spectroscopy, elemental analysis and single crystal X-ray diffractometry. Its aggregation-induced emission behavior was studied by ultraviolet/visible, photoluminescence spectroscopy and scanning electron microscope. Its solid-state mechanochromic and thin-film vapochromic luminescence behaviors were also investigated by photoluminescence spectroscopy. The results demonstrated that luminogen 1 showed obvious aggregation-induced emission property. Furthermore, 1 also exhibited reversible high-contrast mechanochromic and vapochromic luminescence behaviors. More interestingly, 1 can emit persistent room-temperature phosphorescence with a solid-state emission lifetime up to 86.84?ms, which is the highest lifetime value among all the reported gold(I) complexes so far. To the best of our knowledge, the gold(I) complex is the first example of an AIE-active luminogen with persistent room-temperature phosphorescence, reversible mechanochromism and vapochromism characteristics.
