Helical architectures such as DNA and helical motives in proteins may assemble further to form helical superstructures. Engelkamp et al. (p. 785) used similar principles to design molecules that self-assembled into fibers consisting of helical superstructures. The chirality of these fibers can be tuned by the addition of potassium ions, which change the stacking of the molecules in the fibers, resulting in loss of helicity in the fibers. The materials may find use in optoelectronic applications or as sensors.
