Minature versions of Hookean springs can be built from single-handed helical ladder polymers. The spring constants of these molecular springs vary with the helix diameter analogous to classical springs. These new molecular springs provide an alternative mechanism of expansion/contraction controlled by the intrinsic helical geometries of the ladder polymers, which do not unfold under tension unlike
