Enhancing multiphoton absorption in atomically precise (AuAg) 13 clusters via 2-/4-mercaptopyridine ligand positional isomerism

Puntos clave

• This research aims to investigate how ligand isomerism affects the properties of (AuAg)13 nanoclusters, specifically their multiphoton absorption capabilities.
• Synthesis of alloy (AuAg)13 nanoclusters with 2- or 4-mercaptopyridine ligands.
• Characterization of nanocluster properties post-synthesis.
• Comparison of properties based on ligand position.
• Multiphoton absorption properties were significantly modulated by the position of the ligands.
• Clusters with 2-mercaptopyridine exhibited different absorption characteristics compared to those with 4-mercaptopyridine.
