V. Baryshnikov and co-workers also performed DFT investigations into large cyclo-[2n]-carbon to study their aromaticity property and found that the periodic properties of geometric and electronic structure show convergence when 2n > 50, closing to one-dimensional alkyne chain. Recently, similar synthetic route was applied by L. Sun and co-workers successfully to observed that smaller cyclo-[2n]-carbon molecules, C10 and C14, also exist in condense phase. Moreover, Y. Gao and co-workers also obtained dual anti-aromatic C16. It can be believed that another round of related investigations is coming in future.
