摘要:
Quantum dot ligand, preparation method and quantum dot light-emitting device are provided. The quantum dot ligand has a structural general formula as shown in Formula I, X—Y—Z Formula I; wherein X is a coordination group for forming a coordination bond with a quantum dot body; Z is a dissolving group, and the dissolving group is selected from a polar group; Y includes a linking group and a photosensitive group connected with each other, and the linking group is connected between the coordination group and the photosensitive group; the linking group is selected from an alkylene group; the photosensitive group is capable of undergoing bond breaking under light condition such that the quantum dot ligand decomposes into a first unit including the coordination group and the linking group, and a second unit including the dissolving group, and polarity of the first unit is less than polarity of the second unit.
