A two-level model of an organic macromolecule is proposed, initially containing completely filled (HOMO) and empty (LUMO) levels. The interaction of these levels with free-standing and epitaxial graphene is considered within the framework of the standard adsorption approach. sp- and d-metal and a semiconductor (dielectric) are considered as a substrate. In the latter case, these are silicon carbide polytypes. Estimates have shown that the maximum transition of electrons to graphene takes place for the 3C-SiC substrate. Keywords: a two-level model of a macromolecule, single-layer graphene, metal and semiconductor substrates.
