Emergent Circularly Polarized Luminescence from Self-Assembled Chiral-Ligand-Functionalized CsPbBr3 Nanocrystals
Chiral surface ligands can impart optical activity to all-inorganic perovskite nanocrystals, but how this affects chiroptical properties of their assemblies remains unclear. Here we show that self-assembly of CsPbBr3 nanocubes synthesized with a small amount of added chiral ligand N-benzylcinchonidinium bromide (BCD-Br...
