    摘要: In this invention, polyimidazole ligands (PILs) incorporating pendant imidazole moieties for nanocrystal binding and either sulfonatebetaine, carboxybetaine, or phosphocholinebetaine moieties for water-solubilization have been developed. Greatly enhanced stability of nanocrystals (both over time and in wide pH range) was achieved by incorporating multi-dentate imidazole moieties which provide strong coordination of the ligand to the nanocrystal surface and prevent aggregation of nanocrystals. Synthesis of betaine PILs was developed by modifying the synthesis of recently developed PEG containing poly imidazole ligands (PEG PILs). These nanocrystals are compact, water soluble, and biocompatible.

    摘要: A voltage driven light emitting device includes an electroluminescent material and semiconductor nanocrystals, luminescent organic small molecules, mixtures of emissive species molecules, or conductive polymers. The semiconductor nanocrystals, luminescent organic small molecules, mixtures of emissive species molecules, or conductive polymers emit light. The semiconductor nanocrystals, luminescent organic small molecules, mixtures of emissive species molecules, or conductive polymers can be doped to provide desired emission characteristics. Devices that share a substrate and emit more than one color may be conveniently made.
