Quantum dot-containing complex, quantum dot composition including same, light-emitting device including same, and electronic device including same

An electronic device comprising a light-emitting device comprising:

• a first electrode;
• a second electrode being opposite to the first electrode;
• and
• an interlayer comprising an emission layer and provided between the first electrode and the second electrode,
• wherein the interlayer further comprises a quantum dot-containing complex comprising a quantum dot and a ligand, wherein:
• the ligand comprises a compound comprising an anchor portion and a tail portion, and
• the anchor portion comprises a moiety represented by any one selected from among Formulae 1-1 to 1-5,
• wherein, in Formulae 1-1 to 1-5, * indicates a site for bonding with the tail portion,
• the tail portion comprises a C19-C30 alkyl group, a C19-C30 alkenyl group, a —OC18-C30 alkyl group, a —OC18-C30 alkenyl group, a —NHC18-C30 alkyl group, or a —NHC18-C30 alkenyl group, and
• an amount of the ligand is 7.0 wt % or less, based on 100 wt % of the quantum dot-containing complex.
