摘要：

We have synthesized and characterized a new two-dimensional honeycomb architecture resembling a single-layer of atomically precise silver cluster-assembled material (CAM), [Ag-12((SBu)-Bu-t)(6)(CF3COO)(6)(4,4'-azopyridine)(3)] (Ag-12-azo-bpy). The interlayer noncovalent van der Waals interactions within the single-crystals were successfully disrupted, leading to the creation of this unique structure. The optimized Ag-12-azo-bpy CAM demonstrates a valence band that is localized on the Ag-12 cluster node situated near the Fermi energy level. This localization induces electron injection from the linker to the cluster node, facilitating efficient charge transportation along the plane. Exploiting this single-layer structure as a distinctive platform for p-type channel material, it was employed in a field-effect transistor configuration. Remarkably, the transistor exhibits a high hole mobility of 1.215 cm(2) V-1 s(-1) and an impressive ON/OFF current ratio of similar to 4500 at room-temperature.
