Abstract

The invention discloses a ligand exchange method of quantum dots and a quantum dot compound, and the ligand exchange method of the quantum dots comprises the following steps: providing a first PAMAM dendrimer; converting an amino group in the first PAMAM dendrimer into a functional group containing a sulfydryl group to obtain a second PAMAM dendrimer; and mixing the second PAMAM dendrimer with oil-phase quantum dots in a non-polar solvent for ligand exchange to obtain the quantum dots. The second PAMAM dendrimer is combined to the surface of the quantum dots through ligand exchange reaction, and the stability and solubility of the quantum dots can be improved at the same time.

Description

technical field [0001] The invention relates to the field of quantum dots, in particular to a quantum dot ligand exchange method and a quantum dot compound. Background technique [0002] Quantum dots have attracted much attention because they are the most promising nanomaterials. The application of quantum dots has high requirements for their stability and solubility. [0003] There are many ways to improve the stability and solubility of quantum dots, among which the main ways to change the stability of quantum dots are: preparing quantum dots with a core-shell structure, or growing a layer of silica shell on the outer layer of quantum dots, etc.; changing The solubility of quantum dots mainly includes: combining some ligands with better solubility on the surface of quantum dots to improve the solubility of quantum dots. However, there is no technical means in the prior art that can simultaneously improve the stability and solubility of quantum dots, so the prior art still...
