Copper nanoclusters with atomic precision as catalyst for organic reactions.

Area of Science:

• Catalysis
• Nanomaterials Science
• Organometallic Chemistry

Background:

• Atomically precise copper nanoclusters (Cu NCs) bridge molecular catalysts and nanoparticles.
• They offer well-defined structures and electronic properties for direct structure-activity correlations.

Purpose of the Study:

• To review recent advances in using Cu NCs as organocatalysts.
• To highlight structure-activity relationships and design principles for Cu NC catalysts.

Main Methods:

• Summarizing recent literature on Cu NCs in organic transformations.
• Analyzing the impact of structural features on catalytic performance.

Main Results:

• Cu NCs catalyze a wide range of reactions, including cycloadditions, coupling, hydrogenation, and oxidation.
• Catalytic activity and selectivity are governed by nuclearity, ligand dynamics, and electronic states.
• Cu NCs can act as photo- and redox catalysts, exhibiting single-site behavior.

Conclusions:

• Atomically precise Cu NCs are versatile catalysts with tunable properties.
• Understanding structure-activity relationships is key to designing efficient, sustainable copper catalysts.
