Coordinated Anionic Inorganic Module: An Efficient Approach Towards Highly Efficient Blue‐Emitting Copper Halide Ionic Hybrid Structures

Copper halide based organic–inorganic hybrid structures exhibit great potential as light-emitting materials. In their Research Article (e202115225), Wei Liu, Gangfeng Ouyang et al. report a facile strategy for the synthesis of highly luminescent copper halide hybrid structures by fabricating a coordinated anionic inorganic module with a neutral organic ligand molecule. By using this approach, a family of blue-emitting copper halide hybrid ionic structures have been prepared with high internal quantum yields of up to 98 %.
