Chiral Imprinting on Inorganic Nanoparticles for Enantioselective Surface Recognition.

ABSTRACT: Chiral semiconductor nanoparticles, especially metal oxides, hold great potential for selective photocatalysis and enantiomer separation. Chirality in such systems can emerge during nanoparticle nucleation and growth, leading to optical activity in the absorption range of the material. A key aspect of this phenomenon is the transfer of chirality from a chiral organic molecule interacting with the nanoparticle surface to the inorganic core. In this study, threoninol is used as a chiral ligand to induce chirality in titanium dioxide (TiO₂) nanoparticles, and its binding mode to the metal oxide is investigated through nuclear magnetic resonance (NMR) spectroscopy. The analysis reveals that threoninol interacts with the TiO₂ surface primarily via hydrogen bonding through
