Conductive One‐Handed Nanocoils by Coassembly of Hexabenzocoronenes: Control of Morphology and Helical Chirality

One-handed military discipline: The hexabenzocoronene (HBC) derivative 1 can coassemble with the chiral HBCs (S)- or (R)-2 to yield graphitic nanocoils (see picture). Self-assembly of 2 alone gives noncoiled fibrous assemblies. A sergeants-and-soldiers effect leads to the formation of one-handed nanocoils. These can be covalently stabilized by post-surface ROMP of the pendant norbornene groups to give a uniform cast film. Upon doping with I2, this film becomes electroconductive without any detectable morphological disruption.
