Abstract
The present disclosure provides a quantum dot ligand, a quantum dot-ligand system and a quantum dot material, belonging to the field of display technology. The quantum dot ligand includes an X group, a Y group and a Z group. The Y group is configured to provide at least two binding sites, among which at least one binding site is configured to bind with the X group, and the remaining binding site is configured to bind with the Z group. The X group is a coordination group configured to form a coordination bond with a surface of a quantum dot. The Z group is a saturated 3- to 5-membered heterocyclic group containing O or S.
Claims16
A quantum dot ligand, comprising an X group, a Y group and a Z group, wherein:
- the Y group is configured to provide at least two binding sites, among which at least one binding site is configured to bind with the X group and a remaining binding site other than the at least one binding site is configured to bind with the Z group, wherein the Y group comprises at least one binding group selected from alkylene with a carbon atom number ranging from 2 to 12;
- the X group is a coordination group configured to form a coordination bond with a surface of a quantum dot, wherein the X group is selected from an amino group, a carboxylic acid group, a sulfydryl, a phosphine group, a phosphine oxide group, or a saturated heterocyclic group containing a disulfide bond;
- and
- the Z group is a saturated 3- to 5-membered heterocyclic group containing O or S.
A quantum dot-ligand system, comprising a quantum dot, a photo acid generator and a quantum dot ligand, the quantum dot ligand comprising an X group, a Y group and a Z group, wherein:
- the Y group is configured to provide at least two binding sites, among which at least one binding site is configured to bind with the X group and a remaining binding site other than the at least one binding site is configured to bind with the Z group, wherein the Y group comprises at least one binding group selected from alkylene with a carbon atom number ranging from 2 to 12;
- the X group is a coordination group configured to form a coordination bond with a surface of a quantum dot, wherein the X group is selected from an amino group, a carboxylic acid group, a sulfydryl, a phosphine group, a phosphine oxide group, or a saturated heterocyclic group containing a disulfide bond;
- and
- the Z group is a saturated 3- to 5-membered heterocyclic group containing O or S.
A quantum dot-ligand material, comprising at least two quantum dot-ligand units that comprise a quantum dot and a quantum dot ligand, the quantum dot ligand comprising an X group, a Y group and a Z group, the at least two quantum dot-ligand units being mutually bonded and cross-linked to form a mesh structure through ring-opening of the Z group, wherein:
- the Y group is configured to provide at least two binding sites, among which at least one binding site is configured to bind with the X group and a remaining binding site other than the at least one binding site is configured to bind with the Z group, wherein the Y group comprises at least one binding group selected from alkylene with a carbon atom number ranging from 2 to 12;
- the X group is a coordination group configured to form a coordination bond with a surface of a quantum dot, wherein the X group is selected from an amino group, a carboxylic acid group, a sulfydryl, a phosphine group, a phosphine oxide group, or a saturated heterocyclic group containing a disulfide bond;
- and
- the Z group is a saturated 3- to 5-membered heterocyclic group containing O or S.
