Twisted structure is an unprecedented case of a compound that becomes aromatic by breaking its own symmetry

The looped molecule’s unusual shape could unlock strange physical properties

Stereoisomers of C13Cl2 exhibiting helical orbitals around a ring of carbon atoms were synthesized by atom manipulation on NaCl surfaces. We resolved the enantiomeric geometries of the singlet states ...

Cyclo[N]carbons, molecular rings consisting solely of N carbon atoms, have previously been studied in the gas phase and on surfaces at cryogenic temperatures, but they are generally considered too rea...
