Abstract: The present invention provides nanostructure compositions and methods of producing nanostructure compositions. The nanostructure compositions comprise a population of nanostructures comprising polythiol ligands with pendant moieties. The polythiol ligand with pendant moieties increase the solubility of the nanostructures in solvents and resins. The present invention also provides nanostructure films comprising the nanostructure compositions and methods of making nanostructure films using the nanostructure compositions.
