ABSTRACT
The problem of obtaining linear-chain carbon has been of great interest in the past few decades [1,2]. Experimental and theoretical investigations of carbon vapor at high temperatures (T>2000K) have shown that carbon clusters Cn with the sp
1-type hybridization becomes the most stable at temperatures up to 4000K [3-5]. However, these clusters are very reactive and begin to interact with each other and with oxygen at very low temperatures (below 12K) [6,7]. Thus, despite the great interest in and intensive research activity on chain-like carbon, this subject still needs to be investigated further. The most chemically active parts of the carbon chains are their end groups, which can react with end groups of other chains, resulting in cross-linking or formation of chemical bonds with molecules of the gas atmosphere.
