“…Chiral core–shell quantum nanocrystals (NCs), such as chiral CdSe/CdS and CdSe/ZnS with enhanced photoluminescence quantum yields (PLQYs) and environmental stabilities, have recently become an emerging topic of interest because of their promising applications in chiral recognition, − stereoselective synthesis, , biosensing, display devices, − and so forth. − Chiral core–shell quantum NCs also provide an ideal platform for exploring the mechanisms − underlying the chirogenesis of excitonic circular dichroism (CD) and the possibility for controlling circularly polarized luminescence (CPL) through the extensive tunability of the size-dependent fluorescence properties as a result of quantum confinement effects. , Three mechanisms for explaining the induction of chirality in chiral metal nanoparticles , (NPs) are often extended to semiconductor NCs: , (i) intrinsically chiral NCs with dislocations and defects, ,− (ii) ligand-induced chiral surfaces in QDs , or chiral interactions between chiral ligands and achiral QDs, ,, and (iii) achiral QD-based chiral assemblies. − Among these mechanisms, ligand exchange with chiral molecules produces tremendous advances in obtaining QDs with a uniform size distribution and providing diverse choices for designing the surface chemistry of QDs to impart chemical properties. To date, an extensive body of experiments and theoretical calculations have been reported toward discovering the origin and modulating the intensity of chirality with various parameters, including the surface ligand motif , (thiolated or nonthiolated, , number of stereocenters, , and surface ligand conformation when bound to QDs) and chemistry of the QDs, namely, the size and shell thickness of the QDs. , Ferry’s work, for instance, compared carboxylate-bound and thiolate-bound chiral CdSe QDs and showed that chiral carboxylic acids can exhibit int...…”
