Helical conformation is a representative secondary structure of biomacromolecules such as DNA and proteins in nature, and plays an important role in the metabolism of organisms. Partially inspired by such natural biological helices, considerable studies have been conducted on the design and synthesis of polymers with stable helical conformations in recent decades. The objectives of these researches are not only to mimic the structure and function of biological helices, but also to widen their applications i...
