Double helical conformation and extreme rigidity in a rodlike polyelectrolyte

Double helical conformation and extreme rigidity in a rodlike polyelectrolyte

Double helix structures appear widely in nature, but only rarely in synthetic non-chiral macromolecules. Here the authors describe a double helix in a densely charged aromatic polyamide, which exhibits an axial rigidity persistence length of ~ 1 μm, much higher than that of DNA (~ 50 nm).
