On-surface synthesis of a doubly anti-aromatic carbon allotrope.

ABSTRACT: Synthetic carbon allotropes such as graphene¹, carbon nanotubes² and fullerenes³ have revolutionized materials science and led to new technologies. Many hypothetical carbon allotropes have been discussed⁴, but few have been studied experimentally. Recently, unconventional synthetic strategies such as dynamic covalent chemistry⁵ and on-surface synthesis⁶ have been used to create new forms of carbon, including γ-graphyne⁷, fullerene polymers⁸, biphenylene networks⁹ and cyclocarbons^10,11. Cyclo[N]carbons are molecular rings consisting of N carbon atoms^12,13; the three that have been reported to date (N = 10, 14 and 18)^10,11 are doubly aromatic, which prompts the
