a, Examples of ionic metal halides. b,c, Atomistic depiction of surface stabilization (b) and disintegration (c) of APbX3 perovskite by common long-chain cationic (Cat+) and anionic (An−) ligands due to excess ligand quantity and low internal crystal energy. d, Zwitterionic molecules offer stronger (multidentate) binding and reduced reactivity owing to their neutral charge. e, Structural engineering of the head, bridge and tail groups unlocks their broad utility for stabilizing diverse metal halide NCs and dispersing them in various media.
