| Research Abstract |
Graphene, a material having a two-dimensional atomic layer consisting of sp2-hybridized carbon, has attracted intense interests in recent years owing to the unique structure and electronic and optical properties. The functionalization of graphenes with large aromatic molecules is expected to modulate the electronic and optical properties of graphenes by the interactions between the two components in the ground and excited states. In this study, we prepared chemically-converted graphene (CCG) covalently functionalized with porphyrins or pyrenes with a rigid phenylene or oligophenylene spacer and investigated the optical and photophysical properties in detail. In addition, we also fabricated noncovalently-bound binary nanocarbon composite films of fullerene-CCG and ternary composite films of fullerene-carbon nanotubes-CCG on semiconducting electrodes.
