Overview

Investigations demonstrate chirality transfer in gold nanoclusters, suggesting insights for chiral nanomaterials design.

Key Points

  • This work aims to explore how chirality is transferred from gold nanoclusters to their ligands.
  • Utilized vibrational circular dichroism (VCD) spectroscopy for analysis.
  • Applied density functional theory and SCC-DFTB calculations for theoretical modeling.
  • Selected models include Au25(2-MeBuS)18, Au38(2-MeBuS)24, and Au144(2-MeBuS)60 for varying chirality levels.
  • VCD analysis showed that increasing structural chirality leads to greater restriction and reorganization of ligand conformations.
  • Au25 exhibited modest spectral changes due to its achiral nature, while Au38 revealed significant VCD and IR spectral alterations.
  • Au144 demonstrated a pronounced VCD response owing to its chiral gold core, confirming stronger chirality amplification.
