[Cu ₁₈ H ₃ (S-Adm) ₁₂ (PPh ₃ ) ₄ Cl ₂ ]: fusion of Platonic and Johnson solids through a Cu(0) center and its photophysical properties

the Cu(0) center. This NC exhibits violet emission due to kernel-dominated relaxation at room temperature, which is further enhanced by confining the surface protecting ligands through recognition-site-specific host-guest supramolecular adduct formation by β-cyclodextrin. The unique electronic structure of this NC further facilitates its application toward photocurrent generation. Thus, this study offers a unique strategy for the controllable synthesis of a Cu(0)-containing Cu NC, which enables atomic-level insights into their optoelectronic properties.
