A polyyne is any organic compound with alternating single and triple bonds; that is, a series of consecutive alkynes, n with n greater than 1. These compounds are also called polyacetylenes, especiall

…carbon that has the chemical structure (−C≡C−)n as a repeat unit, with alternating single and triple bonds. It would thus be the ultimate member of the polyyne family. This polymeric carbyne is of considerable interest to nanotechnology as its Young's modulus is 32.7 TPa – forty times that of diamond; this…
