Abstract
Recently synthesized cyclo[18]carbon which is characterized as polyyne D9h has a very short lifetime even at 5 K temperature. Its automerization is proposed through a transition state which is reported as a D18h symmetric cumulene.
In the present article, an experimentally viable method for the enhancement of the lifetime of this compound is reported. The carbon nanotube is employed for this purpose. We also report that adopting numerous molecules of cyclo[18]carbon in the womb of a zeolite cage, wire-like countenance construction is feasible.
