Since carbon (C) atom has a variety of chemical bonds hybridization between s and p atomic orbitals, it is well known that there are robust carbon materials. In particular, discovery of C 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 is soluble and volatile unlike nanotube and graphene. This indicates that C film is easy to be produced on any kinds of substrates, which is advantage for device fabrication. In particular, electron-/photo-induced C polymerization finally results in formation of one-dimensional (1D) metallic peanut-shaped and 2D dumbbell-shaped semiconducting C polymers, respectively. This enables us to control the physicochemical properties of C films using electron-/photo-lithography techniques. In this review, we focused on the structures, fundamental properties, and potential applications of the low-dimensional C polymers and other nanocarbons such as C 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.
由于碳原子具有多种化学键，即s和p原子轨道之间的杂化，众所周知存在坚固的碳材料。特别是，富勒烯的发现对培育纳米碳领域具有划时代的意义。从那时起，诸如纳米管和石墨烯等纳米碳材料就被报道了。值得注意的是，富勒烯与纳米管和石墨烯不同，它是可溶且易挥发的。这表明富勒烯薄膜易于在任何种类的衬底上制备，这对器件制造来说是一个优势。特别是，电子/光诱导的富勒烯聚合最终分别导致形成一维（1D）金属花生形和二维哑铃形半导体富勒烯聚合物。这使我们能够使用电子/光刻技术来控制富勒烯薄膜的物理化学性质。在这篇综述中，我们聚焦于低维富勒烯聚合物以及其他纳米碳（如富勒烯豆荚、波浪结构石墨烯和具有拓扑缺陷的五边形纳米管）的结构、基本性质和潜在应用。我们希望这篇综述能为生产新型纳米碳材料提供新的见解，并激发广大读者在碳材料领域开展更多新的研究。
