Abstract: front page image
(EN)Certain dithio- compounds have been found to be superior capping ligands for quantum dot (QD) nanoparticles. Example dithio- ligands include dithiocarbamate ligands. These strongly binding ligands are capable of coordinating to both positive and negative atoms on the surface of the nanoparticle. The ligands are bi-dentate and thus their approach to the QD surface is not as sterically hindered as is the approach of mono-dentate ligands. These ligands can therefore completely saturate the QD surface.
(FR)PM340672WO Page 20 de 20 666 72007 -1-MDAUNCEY L'invention concerne certains composés dithio qui s'avèrent être des ligands de coiffage supérieurs des nanoparticules à points quantiques (QD). Un exemple de dithio-ligands comprend des ligands à base de dithiocarbamate. Ces ligands fortement liants sont capables de se coordonner à la fois à des atomes positifs et négatifs à a surface de la nanoparticule. Les ligands sont bi-dentés et leur approche de la surface QD n'est pas aussi stériquement empêchée que l'approche de ligands monodentés. Ces ligands peuvent donc complètement saturer la surface QD.
