A one-pot in-situ synthesis of copper cluster doped hydrogen substituted graphdiyne nanofibers (Cu-HsGDY)

Graphdiyne (GDY) is a new type of two-dimensional (2D) carbon materials, in which two benzene rings are chained by diacetylenic linkages (-C≡C-C≡C-). γ-GDY the most studied GDY due to its stable configuration and was experimentally obtained 2010 through cross coupling reaction using hexaethynylbenzene as precursor. Hydrogen substituted graphdiyne (HsGDY) 1, 3, 5-triethynylbenzene precursor similar process. Hereinto, copper cluster doped hydrogen nanofibers (Cu-HsGDY) were prepared facile one-pot in-situ synthetic approach good reproductive manner. Through simply removing foil, robust Cu-HsGDY can be transferred onto arbitrary substrates, especially flexible such polyethylene terephthalate (PET), used electronics future materials.
