Abstract
The present invention provides nanostructure compositions and methods of producing nanostructure compositions. The nanostructure compositions comprise a population of nanostructures comprising thiol-functionalized ligands to increase the stability of the composition in thiol resins. The present invention also provides nanostructure films comprising a population of nanostructures comprising thiol-functionalized ligands and methods of making nanostructure films using these nanostructures.
