Abstract
Embodiments of the invention involve semiconductor nanoparticle capping ligands, their production and use. Ligands may have the formula with m ranging from approximately 8 to approximately 45. An embodiment provides a method of forming a compound of the formula including the steps of providing a first starting material comprising poly(ethyleneglycol) and reacting the first starting material with a second starting material comprising a functional group for chelating to the surface of a nanoparticle to thereby form the compound.
Claims22
A ligand having the formula:
- wherein m ranges from 8 to 45.
A method of forming a compound of the formula
- wherein X is an atom or chemical group, Y is an atom or chemical group and m is an integer, the method comprising the steps of:
- providing a first starting material comprising poly(ethyleneglycol);
- and
- reacting the first starting material with a second starting material comprising a functional group for chelating to the surface of a nanoparticle, thereby forming the compound.
A method for producing capped nanoparticles comprising capping at least one nanoparticle with a compound of formula
- wherein X is an atom or chemical group, Y is an atom or chemical group and m is an integer.
Nanoparticles capped with a compound of formula
- wherein X is an atom or chemical group, Y is an atom or chemical group and m is an integer.
A display device comprising:
- a plurality of nanoparticles, each capped with a ligand having the formula
- wherein m is an integer, disposed within a material substantially transparent to light.
