▎ 摘  要

Spatially extended structures of nanosized pi-conjugated regions and fragments of the carbon framework, including their two-dimensional electrically connected percolation networks, were found out and studied in films of graphene oxide (GO) and its thermally reduced derivatives (TRGO) by a set of complementary physical methods,. In films with a nanostructured carbon framework, an unusually high density of charge-carrier states near the Fermi level was discovered using magnetic investigation methods, signifying the existence of specific pi-electronic states (topological zero modes), which can be stabilized in the zigzag parts of carbon network cracks (at zigzag edges of nanographenes). A conclusion is made about a potential suitability of these graphene oxide derivatives for the formation of percolation networks of nanographenes with predominantly zigzag edges in them.
