Helical biomacromolecules such as DNA and polypeptides or proteins play important roles in living systems. Extensive efforts have been devoted to helicity induction in unnatural oligomers, polymers, and dendrimers to explore new properties and functions.[1–3] In many cases, chiral amplification has been observed, which has found applications in molecular recognition,[4] light harvesting,[5] and catalysis.[6] We are motivated to explore new ...
