We attribute this stability improvement to a more robust attachment of the zwitterionic head group to the surface of the NCs, similar to previous demonstrations by others. The advantageous effects of DCzGPC on the electronic properties of CsPbBr2Cl NCs include an increase in the PLQY in solution as well as a largely improved electroluminescence characteristics in solid-state LEDs. While both effects are likely to result from the elimination of unsaturated surface defects compared to the native oleic acid/oleylamine ligands, the higher luminance and larger EQE of the LEDs indicate an additional facilitation of carrier injection, most likely due to the proximity of the -conjugated carbazole moiety. We note that further improvements in the hole injection rate should be possible upon replacing the carbazole backbone of the DCzGPC ligand with other moieties that decrease the ionization energy.
