Embodiments of the invention relate to a process for the production of surface functionalised nanoparticles, such as semiconductor quantum dot nanoparticles incorporating surface-bound functional groups suitable for enabling the dots to be incorporated into silicone polymers.
A process for the production of surface functionalised nanoparticles, such as the production of semiconductor quantum dot nanoparticles incorporating surface-bound functional groups that increase the ease with which the dots can be employed in applications, such as incorporation into solvents, inks, polymers, glasses, metals, electronic materials and devices, bio-molecules and cells. Embodiments of the method include reacting first and second nanoparticle precursor species in the presence of a nanoparticle surface binding ligand X—Y—Z where X is a nanoparticle surface binding group, Y is a linker group, and Z is a functional group, in which Y comprises a polyethyleneglycol group and/or Z comprises an aliphatic group incorporating a terminal unsaturated group, the reaction being effected under conditions permitting binding of said surface binding ligand to the growing nanoparticles to produce said surface functionalised nanoparticles.

Redox-active nanoparticle-cored dendrimers were synthesized by a stepwise reaction, in which synthesis of functionalized nanoparticles was followed by organic reactions to build dendritic architecture around a nanoparticle core. Incorporation of redox molecules on the surface of nanoparticles resulted in the formation of a redox-active nanoparticle-cored dendrimer.
