Gangloff et al . describe the influence of dispersity on the self‐assembly of amphiphilic block copolypeptoids by directly comparing diblocks that differ only in the dispersity of their building blocks, and not in their average composition. The uniformity of the hydrophobic block appears to be a crucial feature for creating sharp interfaces, seen in AFM images. (Polymers in the top images are uniform, those in the bottom images are disperse.) Calorimetry measurements of the hydrophobic homopolymers reveal that the transition from oligomer to polymer is not just dependent on the average chain length, but also on the dispersity of the material.
