Since carbon (C) atom has a variety of chemical bonds via hybridization between s and p atomic orbitals, it is well known that there are robust carbon materials. In particular, discovery of C 60 has been an epoch making to cultivate nanocarbon fields. Since then, nanocarbon materials such as nanotube and graphene have been reported. It is interesting to note that C 60 is soluble and volatile unlike nanotube and graphene. This indicates that C 60 film is easy to be produced on any kinds of substrates, which is advantage for device fabrication. In particular, electron-/photo-induced C 60 polymerization finally results in formation of one-dimensional (1D) metallic peanut-shaped and 2D dumbbell-shaped semiconducting C 60 polymers, respectively. This enables us to control the physicochemical properties of C 60 films using electron-/photo-lithography techniques. In this review, we focused on the structures, fundamental properties, and potential applications of the low-dimensional C 60 polymers and other nanocarbons such as C 60 peapods, wavy-structured graphene, and penta-nanotubes with topological defects. We hope this review will provide new insights for producing new novel nanocarbon materials and inspire broad readers to cultivate new further research in carbon materials.

“…Onoe et al have synthesized carbon polymers, which are generated by electron-beam irradiation to C 60 films and called 1D peanut-shaped C 60 polymers (PSFPs) . The 1D PSFPs have positive and negative Gaussian curvatures and have shown interesting phenomena such as Tomonaga–Luttinger liquid states and anomalous electron transport properties. , Although they have used the infrared (IR) spectroscopy, − their geometrical structure has not been clarified so far. Quite recently, we have studied the electronic band structures of several 1D PSFPs and corrugated graphene systems with pentagons, hexagons, heptagons, and octagons using density functional theory (DFT) .…”

In the present study, we investigate different types of 1D peanut-shaped fullerene polymers (PSFPs) using density functional theory to understand the electronic states and the energetic stability of curved carbon nanomaterials. We generated 53 different models of the 1D PSFPs by means of the generalized Stone-Wales transformations and performed structural optimization for each model. Band structures of the 1D PSFPs exhibit either metallic or semiconducting property according to the geometrical structures. We find that the energetic stability of the 1D PSFPs depends on the geometry: the more octagon and pentagon-octagon pairs (heptagons and hexagon-heptagon pairs) in their geometrical structures, the more stable (unstable) the 1D PSFPs.

We performed in situ four-probe measurements of the current-voltage characteristics of one-dimensional (1D) uneven peanut-shaped C60 polymer films in the temperature range 30–350 K under ultrahigh vacuum conditions (2 × 10−7 Pa). Arrhenius plots of the film resistance with respect to temperature showed two different electron-conduction mechanisms. While electrons are conducted via a thermal excitation hopping at temperatures above 160 K, the resistivity of the 1D polymer film exhibits an anomalous behavior that becomes fluctuated at a given value in the temperature range 40–90 K and decreases at temperatures below 40 K.
