Integrating Rigidity and Regular Packing in Ag6 Clusters via Ligand Fluorination: Toward High-Efficiency Low-Loss Optical Waveguiding.
Ligand fluorination offers an effective approach to regulate both molecular packing and excited-state properties in metal nanoclusters for optical waveguiding. In this study, a series of Ag6L6 clusters, Ag6(PPT)6, Ag6(FPPT)6, and Ag6(2FPPT)6, were constructed using stepwise fluorinated ligands. All three clusters featu...
