prof. Ken ItamiNanocarbons conduct electricity, absorb and emit light, and exhibit interesting magnetic properties. At present, however, synthetic routes to nanocarbons mainly lead to mixtures of molecules with a range of different structures and properties, which cannot be easily separated or refined into pure forms. Obtaining “pure" nanocarbons is a great challenge in the field of nanocarbon science and technology. Toward addressing this grand challenge in nanocarbon science, we are trying to synthesize structurally uniform nanocarbons and a new form of carbons (Nature Rev Mater 2016). To achieve this goal, the development of new reactions and catalysts has been the key. For example, our powerful palladium catalyst can promote the regioselective aromatic π-extension (APEX) of polycyclic aromatic hydrocarbons (PAHs). This C-H activation methodology can be applied to various planar and geodesic PAHs to generate graphene nanoribbons (Science 2018, Nature Comm 2015) and three-dimensional warped nanographenes (Nature Chem 2013). In addition to the above-mentioned chemistry of nanoribbons and saddles, our synthetic campaign toward carbon nanotubes (Nature Chem 2013, Nature Comm 2018 and carbon nanobelts (Science 2017) will also be described.
