Abstract

The invention pertains to the field of nanotechnology. The disclosure provides nanostructure compositions comprising (a) at least one organic solvent; (b) at least one population of nanostructures comprising a core and at least one shell, wherein the nanostructures comprise inorganic ligands bound to the surface of the nanostructures; and (c) at least one poly(alkylene oxide) additive. The nanostructure compositions comprising at least one poly(alkylene oxide) additive show improved solubility in organic solvents. And, the nanostructure compositions show increased suitability for use in inkjet printing. The disclosure also provides methods of producing emissive layers using the nanostructure compositions.
