Abstract
Siloxane polymer ligands for binding to quantum dots are provided. The polymers include a multiplicity of amine or carboxy binding ligands in combination with long-alkyl chains providing improved stability for the ligated quantum dots. The ligands and coated nanostructures of the present invention are useful for close packed nanostructure compositions, which can have improved quantum confinement and/or reduced cross-talk between nano structures.
