Inorganic nanocrystals with an organic coating and preparation process thereof

摘要

The nanocrystals comprising a metal and/or a semi-conductor are coated with an organic material comprising a ligand. - The nanocrystal comprises an inorganic core consisting of a metal and/or metal semi-conductor, the external surface being coated with an organic material constituted by a ligand of formula : X-Y-Z (I) : in which X is a 1,1-dithiolate or 1,1-diselenoate group linked by the two atoms of S or Se to a metal atom at the external surface, Y is a spacer group, to allow transfer of charge or an isolating group, and Z is a group which is capable of producing certain specific properties to the nanocrystal. An INDEPENDENT CLAIM is also included for the preparation of the compounds.
