In order to explore novel functional nanomaterials, we have produced sp(2)-sp hybrid carbon structures composed of graphene layers (2D) and linear carbon chains (1D). A remarkable change of the graphene electronic and phononic behaviour is observed after the interaction with 1D carbon nanostructures. Raman and surface enhanced Raman spectroscopies together with a density functional theory approach are used to explain charge transfer phenomena as a function of linear molecule orientation in the produced 1D-2D carbon-based structures, inducing hole-doping in graphene layers.

Abstract
In order to explore novel functional nanomaterials, we have produced sp(2)-sp hybrid carbon structures composed of graphene layers (2D) and linear carbon chains (1D). A remarkable change of the graphene electronic and phononic behaviour is observed after the interaction with 1D carbon nanostructures. Raman and surface enhanced Raman spectroscopies together with a density functional theory approach are used to explain charge transfer phenomena as a function of linear molecule orientation in the produced 1D-2D carbon-based structures, inducing hole-doping in graphene layers.
