## Abstract The remarkable ease with which 1,3,14,16‐tetramethylhexahelicene can be oxidised has to be ascribed to the electronic effect of multiple methyl substitution and not to disturbance of the helical conformation, as might be concluded from the polarographic oxidation potentials of hexahelic

## Abstract Seven new hexahelicenes (**3−7**, **9**, **10**) containing different functional group substituents have been synthesized and, in three cases (**4**, **8**, **10**), optically resolved. Optical rotations were measured and CD spectra are reported. X‐ray crystal structures of the helicene
