Special Issue Information

Dear Colleagues,

Carbon allotropes show various structures, ranging from three-dimensional, two-dimensional, to one-dimensional (1D), and electrical conductance ranges from conductor, semiconductor, to insulator. One-dimensional allotropes of carbon, e.g., carbon nanotubes, graphene nanoribbons, and carbon chains, demonstrate carbon materials with superior properties, leading to the development of cutting-edge studies of low-dimensional materials. Although their synthesis, properties, and applications have been extensively studied previously, scientists are still faced with an increasing number of challenges. For example, the precision and/or large-scale synthesis of 1D carbon allotropes with specific structures are still under exploration, including single-chiral carbon nanotubes, edge-defined graphene nanoribbons, length-controlled carbon chains, etc.

This Special Issue aims to present comprehensive research outlining progress on the preparation, properties, and applications of 1D carbon nanomaterials. We invite authors to contribute original research articles and review articles covering the current progress made on 1D carbon nanomaterials. Potential topics include, but are not limited to, the following:

  1. Precision or large-scale synthesis of 1D carbon nanomaterials, e.g., carbon nanotubes, graphene nanoribbons, carbyne;
  2. Applications of 1D carbon nanomaterials;
  3. Heterostructures of 1D carbon nanomaterials;
  4. Carbon-nanotube encapsulation;
  5. Theoretical simulation and/or calculation on the structures and/or properties of 1D carbon nanomaterials;
  6. Polyyne, cumulene, and cyclo[n]carbon;
  7. Other 1D carbon nanomaterials, e.g., carbon fiber and carbon wire.

Abstract
Polyyne is an sp-hybridized linear carbon chain (LCC) with alternating single and triple carbon–carbon bonds. Polyyne is very reactive; thus, its structure can be easily damaged through a cross-linking reaction between the molecules. The longer the polyyne is, the more unstable it becomes. [...] Read more.
Polyyne is an sp-hybridized linear carbon chain (LCC) with alternating single and triple carbon–carbon bonds. Polyyne is very reactive; thus, its structure can be easily damaged through a cross-linking reaction between the molecules. The longer the polyyne is, the more unstable it becomes. Therefore, it is difficult to directly synthesize long polyynes in a solvent. The encapsulation of polyynes inside carbon nanotubes not only stabilizes the molecules to avoid cross-linking reactions, but also allows a restriction reaction to occur solely at the ends of the polyynes, resulting in long LCCs. Here, by controlling the diameter of single-walled carbon nanotubes (SWCNTs), polyynes were filled with high yield below room temperature. Subsequent annealing of the filled samples promoted the reaction between the polyynes, leading to the formation of long LCCs. More importantly, single chiral (6,5) SWCNTs with high purity were used for the successful encapsulation of polyynes for the first time, and LCCs were synthesized by coalescing the polyynes in the (6,5) SWCNTs. This method holds promise for further exploration of the synthesis of property-tailored LCCs through encapsulation inside different chiral SWCNTs. Full article
