Method for solventless quantum dot exchange

摘要

The present invention describes a solventless ligand exchange using a siloxane polymer having a binding ligand that displaces the binding ligand on a quantum dot material.

1. A method for replacing a first ligand on a quantum dot with a second ligand, the method comprising:
mixing a reaction mixture comprising a plurality of quantum dots having the first ligand non-covalently bound to the quantum dots, and a siloxane polymer comprising the second ligand, such that the second ligand displaces the first ligand and becomes non-covalently bound to the quantum dots without using solvent, and wherein the siloxane polymer has a Tg of less than about 100° C. and a viscosity of less than about 1000 cSt, thereby replacing the first ligand on the quantum dot with the second ligand.
