The linear carbon chain (LCC) has attracted much attention regarding its structure and applications. For LCC synthesis, one major advancement was achieved by using double-walled carbon nanotubes (DWCNTs) as the host and annealing at 1460°C, resulting in long chains containing more than 6,000 carbon atoms. In addition to DWCNTs, LCC synthesis using single-walled carbon nanotubes (SWCNTs) has also been reported. However, compared to DWCNTs, the synthesis efficiency with SWCNTs is lower due to their instability at higher temperature. Therefore, we report an efficient LCC synthesis method using SWCNT at a low temperature (400°C).
