Driving oxygen coordinated ligand exchange at nanocrystal surfaces using trialkylsilylated chalcogenides

Author affiliations

Abstract

A general, efficient method is demonstrated for exchanging native oxyanionic ligands on inorganic nanocrystals with functional trimethylsilylated (TMS) chalcogenido ligands. In addition, newly synthesized TMS mixed chalcogenides leverage preferential reactivity of TMS–S bonds over TMS–O bonds, enabling efficient transfer of luminescent nanocrystals into aqueous media with retention of their optical properties.
