Abstract:
A new, straightforward method for the phase-transfer of CdSe@ZnS quantum dots from non-polar solvents into water and short-chained alcohols using amphiphilic hyperbranched polyethylenimine of different molar weights is suggested and the experimental procedure is discussed as well as the chemical properties of the resulting polymer-derivatised nanocrystals.
