▎ 摘　　要

Carbon is a unique and very versatile element which is capable of forming different architectures at the nanoscale. Over the last 20 years, new members of the carbon nanostructure family arose, and more are coming. This review provides a brief overview on carbon nanostructures ranging from C-60 to graphene, passing through carbon nanotubes. It provides the reader with important definitions in carbon nanoscience and concentrates on novel one- and two-dimensional layered carbon (sp(2) hybridized), including graphene and nanoribbons. This account presents the latest advances in their synthesis and characterization, and discusses new perspectives of tailoring their electronic, chemical, mechanical and magnetic properties based on defect control engineering. It is foreseen that some of the structures discussed in the review will have important applications in areas related to electronics, spintronics, composites, medicine and many others.
