Two-Way Transformation between fcc- and Nonfcc-Structured Gold Nanoclusters

Area of Science:

• Nanomaterials Science
• Crystallography
• Physical Chemistry

Background:

• Precise structural control of nanomaterials is crucial for tailoring their properties and applications.
• While non-face-centered cubic (fcc) to fcc transformations in gold nanoclusters are known, the reverse and two-way transformations remain unexplored.

Purpose of the Study:

• To develop a novel synthesis method for achieving two-way structural transformation in gold nanoclusters.
• To investigate the stability of gold nanoclusters with varying structures.
• To synthesize and structurally characterize a novel gold nanocluster.

Main Methods:

• Novel synthesis approach for controlled structural transformation.
• Single-crystal X-ray crystallography for structural resolution.
• Stability studies of different nanocluster structures.

Main Results:

• Successfully demonstrated a two-way structural transformation between face-centered cubic (fcc) and non-fcc structures in gold nanoclusters.
• Synthesized and determined the precise structure of a novel gold nanocluster.
• Evaluated the stability of gold nanoclusters across different structural configurations.

Conclusions:

• The developed method enables unprecedented control over gold nanocluster structures.
• This work advances the understanding of structure-property relationships in gold nanoclusters.
• Potential for new applications of gold nanoclusters through tailored structural design.
