Abstract

Abstract : Fluorous liquid-soluble semiconductor nanocrystals enable the solution-casting of inorganic films on top of an organic small-molecular hole-transporting layer, providing stacked structures suitable for light-emitting diode fabrication. Abstract : This communication reports a materials handling strategy based on fluorous materials chemistry using CdSe/CdS/CdZnS core–shell type semiconductor nanocrystals. When the crystals were treated with the semi-perfluoroalkanethiol ligands in the presence of i Pr2 EtN, the surface-modified nanocrystals (RF 1-NC andRF 2-NC ) became soluble in the fluorous liquids. Solutions ofRF 1-NC andRF 2-NC in HFE-7500 enabled the solution-casting of nanocrystalline films on top of a small-molecular hole-transporting layer and provided layered structures suitable for light-emitting diode fabrication.
