Abstract:
From an interplay of high-resolution UHV-STM imaging and DFT calculations, we have achieved on-surface synthesis of graphyne nanowires through stepwise reactions involving two different types of dehalogenative homocoupling reactions (i.e., C(sp3)-Br and C(sp2)-Br). This study would further supplement our database of on-surface synthesis and provide us with an alternative and efficient strategy for the fabrication of desired nanostructures/nanomaterials.
