ABSTRACT
In Chapter 2, graphene is discussed from the viewpoint of physics.
When a graphene sheet is cut into nano-size fragments, nano-size
graphene, which is called nanographene, is created.
Nanographene is a two-dimensional material with a hexagonal
network of sp2-carbons. In nanographene, one can see the structures
of many polycyclic aromatic hydrocarbons (PAHs) such as hexaben-
zocoronene, perylene, anthracene, and naphthalene, and ultimately
benzene. This means that the property of PAHs would be related
to that of nanographene. Accordingly, in this chapter, we discuss
nanographene from the viewpoint of PAHs.
