Electronic Structure Modulation via Composition‐Preserving Phase Transformations in Metal–Organic Assemblies on the Surface (Small 23/2026)

Supramolecular Self-Assemblies In the Research Article (e13441), Emiko Kazuma, Minhui Lee, Yousoo Kim, and co-workers demonstrate the stepwise phase transformation of metal–organic assemblies on Ag(111), in which the composite units and chemical composition remain unchanged. The modulation of the electronic structure during this phase transformation is systematically investigated. These findings contribute to the understanding of interactions governing metal–organic assemblies on surfaces and suggest a novel strategy for tuning interfacial properties.
