Light-induced access to a fluorescent Cd₇Ag₂₁ nanocluster from a halide-supported Cd₈X nanocluster directed by a face-capping macrocyclic metalloligand.

ABSTRACT: Metalloligands with multiple preorganized binding sites provide unique advantages for modulating structural patterns and enhancing the surface stability of metal nanoclusters. However, the precise structure-directing effect of metalloligands in nanocluster transformation remains a missing puzzle piece. Herein, three nested concentric bitetrahedral Cd₈X nanoclusters were synthesized through a stepwise evolutionary pathway. These nano-sized architectures comprise tetrahedrally arranged tripodal Cd^II macrocyclic metalloligands encapsulating a halide-supported Cd₄ tetrahedron, and the template effect of halide ions on the stabilization of Cd₈X was dependent on their ionic size. Initiated by Ag^I, the released metalloligands from Cd₈
