The invention relates to the synthetic functionalization of an anthraquinone molecule that is substituted with at least one hydroxyl or amino group. In some aspects of the invention a mixture containing said anthraquinone starting material, an aldehyde, a base, an optional solvent, and an optional catalyst is reacted with hydrogen and then with an oxidant. In other aspects of the invention the synthetic functionalization of the anthraquinone molecule takes place electrochemically rather than chemically, through the use of a divided electrolytic cell.

The present disclosure relates to a ligand for a quantum dot, a ligand quantum dot, a quantum dot layer and a method for patterning the same. The surface of the ligand quantum dot of the present disclosure is connected with the cleavage-type ligand including a first ligand unit A, a cleavage unit B, and an adhesion adjusting unit C. The method includes: providing a substrate; coating a mixture containing the ligand quantum dot on the substrate to form a quantum dot film; exposing a preset region of the quantum dot film to ultraviolet light, so that the cleavage unit B in the cleavage-type ligand undergoes a photolysis reaction, and a molecular segment containing the adhesion adjusting unit C and obtained after decomposition is detached from a surface of the quantum dot; and washing off an unexposed region of the quantum dot film with an organic solvent, followed by drying.
