Graphyne (GY) and graphdiyne (GDY)-based monolayers represent the next generation two-dimensional (2D) carbon-rich materials with tunable structures and properties surpassing those of graphene. However, the detection of band formation in atomically thin GY/GDY analogues has been challenging, as both long-range order and atomic precision have to be fulfilled in the system. Here, we report direct evidence of band formation in on-surface synthesized metallated Ag-GDY sheets with mesoscopic (∼1 µm) regularity...
