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

Macrocyclic metalloligand released from a chloride-templated Cd8Cl nanocluster under the initiation of Ag I behaves as a structure-directing agent to manipulate the light-activated generation of a yellow-emissive superatomic Cd7Ag21 nanocluster.
