Using CO-functionalized tips, we generate the odd-numbered cyclocarbon molecule cyclo[13]carbon (C13) on an ulatra-thin insulating film by applying voltage pulses to a stable precursor molecule. The geometric and electronic properties of C13 were characterized experimentally as well as theoretically, determining the electronic ground state to be an open-shell triplet. In addition to the C13 monomer, we also generated its dimer, cyclo[26]carbon, from two precursor molecules [1].
