Ag22 nanoclusters protected by a metallamacrocyclic monolayer were synthesized in high yields by in-situ ligand formation strategy. The high-electron-affinity triazine-based cyanurate ligands 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 thermally activated delayed fluorescence
通过原位配体形成策略,以高产率合成了四个由金属大环单层保护的同构 Ag 22纳米团簇。高电子亲和性三嗪基氰脲酸酯配体赋予团簇独特的核-壳界面键合结构和供体-受体型电子结构,形成第一个具有热激活延迟荧光(TADF)特性的混合价Ag 0/I纳米团簇.
