Comb‐like poly(β‐aspartate)s that adopt layered arrangements with well‐defined phase transitions are revealed here. Outstanding thermochromic effects are displayed by these materials under polarized light, with a rapid, fully reversible color response that is highly sensitive to temperature (see Figure) and that can be adjusted by copolymerization.
