Spring loaded : The smallest members of a family of carbon nanocoils (CNCs), adopting a fixed helical structure, have been synthesized by introduction of one or two staples in o ‐phenylene ethynylene oligomers. The chiroptical responses of the systems having enantiopure L ‐tartrate‐derived staples confirmed the induced helicity. Theoretical studies suggest that these CNCs are pseudoelastic.
