Title:
QUANTUM DOT LIGAND, QUANTUM DOT MATERIAL, AND QUANTUM DOT LIGHT EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/051279
Kind Code:
A1
Abstract:
The embodiments of the present disclosure provide a quantum dot ligand, a quantum dot material, and a quantum dot light emitting device. In the quantum dot ligand represented by general formula (I), n = 1, 2, 3, or 4; two groups among X, Y, and Z are respectively G1 and G2 groups, and the remaining one group is selected from the G1 group, the G2 group, and hydrogen, wherein the G1 group is independently selected at each occurrence from -(CH2)m-L-(CH2)n-R1, where R1 is a coordination group, m is 0-6, n is 0-6, and L is a divalent group or does not exist; and the G2 group is independently selected at each occurrence from a C4-20 alkyl chain in which the number of carbon atoms is greater than 4.
