Self‐assembled monolayers (SAMs) play an important role in materials synthesis and applications. On page 4894, F. Ding and co‐workers illustrate thermodynamic renditions of two immiscible ligands evolving from phase‐separated, striped, and mixed initial states on the surface of a gold nanoparticle. While the mixed state is a common endpoint, weakly striped patterns only occur for a subset of molecular systems, and often at short range and low temperatures. This study highlights the contributions of both entropy and enthalpy in determining binary SAM systems.
