Hexanuclear Zn(II)-Induced Dense π-Stacking in a Metal–Organic Framework Featuring Long-Lasting Room Temperature Phosphorescence

A new strategy to enhance the room temperature phosphorescence performance has been developed through hexanuclear Zn(II)-cluster-induced dense π-stacking in a metal-organic framework matrix. The synergistic effect of metal clusters and large overlap of π-conjugated dimers facilitate the phosphorescence emission, migration, and separation of charge carriers for excellent photocatalytic activity.
