Semiconductor nanoparticle capping ligands, their production and use. An aspect of the present invention provides a ligand having the formula (I) : wherein m ranges from approximately 8 to approximately 45. A further aspect provides a method of forming a compound of the formula (II), 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.

L'invention concerne des ligands de coiffage de nanoparticules semi-conductrices, leur production et leur utilisation. Selon un aspect, l'invention concerne un ligand représenté par la formule (I) dans laquelle m est compris entre environ 8 et environ 45. Selon un autre aspect, l'invention concerne un procédé de formation d'un composé représenté par la formule (II), ledit procédé comprenant les étapes qui consistent à utiliser un premier matériau de départ renfermant un polyéthylèneglycol et à faire réagir le premier matériau de départ avec un second matériau de départ comprenant un groupe fonctionnel pour chélation sur la surface d'une nanoparticule.
