Document Type and Number:

Japanese Patent JP2006192533

Kind Code:

A

Abstract:

To provide an inorganic nanocrystal provided with an organic coating layer, and to provide a material composed of the nanocrystal.

The nanocrystal comprises an inorganic core consisting of at least one metal and/or at least one semiconductor compound comprising at least one metal, the external surface of said nanocrystal being provided with an organic coating layer, consisting of at least one ligand compound of formula (I): X-Y-Z in which X represents a 1,1-dithiolate or 1,1-diselenoate group that is linked by the two atoms of sulphur or selenium to an atom of metal of the external surface of said nanocrystal: Y represents a spacer group, such as a group capable of allowing a transfer of charge or an insulating group; Z is a group chosen from among groups capable of communicating specific properties to the nanocrystal. Their methods of manufacture are also provided.
