Claim 6:
7. A method for manufacturing a quantum dot material comprising steps of:
providing a solution of a ligand compound, wherein reacting 3,6-dibromocarbazole with a boric acid compound to obtain an intermediate, wherein the boric acid compound has a structural formula of, with group R being a coordinating group or a crosslinking group, such that the group R of the boric acid compound replaces the bromine in 3,6-dibromocarbazole, and the intermediate has a structural formula of, and reacting the intermediate with a bromo-compound to obtain the ligand compound, wherein the bromo-compound has a structural formula of R1-Br, with group R1 comprising the coordinating group or the crosslinking group as a terminal group, such that the group R1 replaces the hydrogen in the imine group of the intermediate, wherein R1 is a coordinating group when R is a crosslinking group, or R1 is a crosslinking group when R is a coordinating group;
providing a solution of an initial quantum dot, wherein the initial quantum dot comprises a quantum dot body; and
mixing the solution of a ligand compound with the solution of an initial quantum dot solution, such that the ligand compound reacts with the quantum dot body, wherein the coordinating group of the ligand compound is bonded to the quantum dot body to provide the quantum dot material.
