The work of his group has centered on catalyst-enabling synthetic chemistry with broad directions. Representative projects include (1) development of new catalysts for C-H coupling, (2) synthesis and properties of bio-molecules, (3) synthesis and properties of new optoelectronic -materials, and (4) controlled synthesis of nanocarbons.

1. A grossly warped nanographene and the consequences of multiple odd-membered-ring defects
Kawasumi, K.; Zhang, Q.; Segawa, Y.; Scott, L. T.; Itami, K. Nat. Chem 2013, 5, 739–744.
Graphite, the most stable form of elemental carbon, consists of pure carbon sheets stacked upon one another like reams of paper. Individual sheets, known as graphene, prefer planar geometries as a consequence of the hexagonal honeycomb-like arrangements of trigonal carbon atoms that comprise their two-dimensional networks. Defects in the form of non-hexagonal rings in such networks cause distortions away from planarity. Herein we report an extreme example of this phenomenon. A 26-ring C80H30 nanographene that incorporates five seven-membered rings and one five-membered ring embedded in a hexagonal lattice was synthesized by stepwise chemical methods, isolated, purified and fully characterized spectroscopically. Its grossly warped structure was revealed by single-crystal X-ray crystallography. An independent synthetic route to a freely soluble derivative of this new type of ‘nanocarbon’ is also reported. Experimental data reveal how the properties of such a large graphene subunit are affected by multiple odd-membered-ring defects.
2. Initiation of carbon nanotube growth by well-defined carbon nanorings
Omachi, H.; Nakayama, T.; Takahashi, E.; Segawa, Y.; Itami, K. Nat. Chem. 2013, 5, 572–576.
Carbon nanotubes (CNTs), tubular molecular entities that consist of sp2-hybridized carbon atoms, are currently produced as mixtures that contain tubes of various diameters and different sidewall structures. The electronic and optical properties of CNTs are determined by their diameters and sidewall structures and so a controlled synthesis of uniform-diameter, single-chirality CNTs—a significant chemical challenge—would provide access to pure samples with predictable properties. Here we report a rational bottom-up approach to synthesize structurally uniform CNTs using carbonnanorings (cycloparaphenylenes) as templates and ethanol as the carbon source. The average diameter of the CNTs formed is close to that of the carbon nanorings used, which supports the operation of a ‘growth-from-template’ mechanism in CNT formation. This bottom-up organic chemistry approach is intrinsically different from other conventional approaches to making CNTs and, if it can be optimized sufficiently, offers a route to the programmable synthesis of structurally uniform CNTs.
