Due to their precise atomic structures,photoluminescent copper nanoclusters(Cu NCs)have promising applications in basic research and technical applications,such as bioimaging,cell labeling,phototherapy,and photoactivation catalysis.In this work,we report a simple strategy for synthesizing novel CuNCs co-protected by alkynyl and phosphine ligands with the molecular formula[Cu7(PPh3)10(PE)3(CH3O)](Cu4@Cu3).Single-crystal X-ray crystallography reveals that the NC core exhibits an open square structure and an overall pyramid shape.Two Cu4@Cu3 units are connected through weak interactions to form dimers in crystals,creating a molecular cage that looks like two tightly closed bowls.Cu4@Cu3 exhibits dual emission in the visible region.It is also an aggregation-induced emission(AIE)-active luminescent substance,which exhibits strong emission in the visible light region when aggregated.Besides,it has the properties of radioluminescent(RL)and could be a potential scintillator material.This study not only enriches the types of atomically accurate AIE clusters,but also holds significant importance for the development of a new generation of high-performance and environmentally friendly X-ray scintillators.
