Moreover, all bonds between boron and nitrogen in B9N9 molecule are single one. Study bonding characters for C6, C12, C16, and C20 molecules have confirmed that carbon-carbon bonds of cyclo[n]carbon changed gradually from double bonds to alternating single and triple bonds with increasing n value. The data from theory would give help for future research on C18 and B9N9 molecules in experiment. Graphical abstract Theoretical investigation for bond and spectra characters of cyclo[18]carbon (C18), prepared with low-temperature STM-AFM (s
