Nanoclusters with Thermally Activated Delayed Fluorescence Protected by Ag/Cyanurate/Phosphine Metallamacrocyclic Monolayers through In‐Situ Ligand Transesterification
Ag22 nanoclustersprotected by a metallamacrocyclicmonolayer were synthesized in high yields by in-situ ligand formation strategy. The high-electron-affinity triazine-based cyanurateligands endow the clusters with unique core-shell interfacial bonding structure and donor-acceptor type electronic structure, resulting in the first mixed valence Ag0/I nanocluster with thermallyactivateddelayed fluorescence
