Cooperative assembly . plays an important role in the construction of highly stimuli‐responsive functional surfaces. In their Full Paper on page 13569 ff. , K. Matsuda et al. report on the relationship between molecular structure and the cooperative assembly of molecular ordering. Quantitative analysis of concentration dependence of surface coverage using a nucleation–elongation model reveals that the length of alkyl chain, hydrogen bonds, and photoisomerization have a significant effect on the adsorption parameters at a liquid–solid interface. These insights enable the precise control of cooperativity in 2D self‐assembly by a careful design of molecular structure.
