Syntheses of Heteroatom Substituted and Three Dimensional Nanocarbon Materials on Surface

Since the invention of scanning tunnelling microscopy and atomic force microscopy, the manipulation of single atoms and molecules has attracted tremendous interests of researchers. Particularly, combining with bond-resolved scanning probe microscopy, this field has been rapidly developed. In this contribution, I will present current topics from our group, including on-surface syntheses of three-dimensional and heteroatom substituted nanocarbon materials. The unique structure of these compounds enabled systematic tip-induced chemical reactions, syntheses of the highly reactive diradical products. Their electronic and magnetic properties were analyzed using low-temperature scanning tunneling microscopy. Additionally, we synthesized the spin-1/2 Heisenberg molecular chain and characterized their magnetic couplings.
