Abstract:
Disclosed are a quantum dot composite, an intermediate and a preparation method therefor and the use thereof. The quantum dot composite comprises: quantum dots; and a plurality of polymeric chain ligands, wherein each polymeric chain ligand comprises a coordination unit and at least one polymeric chain, the coordination unit connects the quantum dot and the polymeric chain, and the molecular weight distribution of the polymeric chain is not more than 1.3. The quantum dot surface of the quantum dot composite coordinate bonds a plurality of polymeric chain ligands, and the length of the polymeric chain thereof is precisely controllable, wherein same can effectively adjust and control the viscosity and surface tension of ink containing the quantum dot composite, and therefore, the use of an additive can be avoided, a low boiling-point solvent can also be used, and the purity of the quantum dot in the ink can be guaranteed.
