Quantum dot luminescent material, quantum dot patterning method, quantum dot film and display device

Abstract

A quantum dot luminescent material, a quantum dot patterning method, a quantum dot film, and a display device. The quantum dot luminescent material includes a plurality of quantum dots; a plurality of ligands attached to the quantum dots; a plurality of crosslinking reactants configured to undergo a crosslinking reaction to connect at least two of the quantum dots and the crosslinking reactants being a plurality of crosslinking molecules or a plurality of crosslinking groups; wherein the quantum dots and the crosslinking reactants satisfy at least one of Condition (1), Condition (2), or a combination thereof: Condition (1): the crosslinking reactants have a lowest unoccupied molecular orbital (LUMO) energy level that is located outside a bandgap of the quantum dots; and Condition (2): the crosslinking reactants have a highest occupied molecular orbital (HOMO) energy level that is located outside the bandgap of the quantum dots.
