Beyond Cocrystals: Hierarchical Functional Assemblies via Noncovalent Synthesis
Advanced Science, EarlyView.Non‐covalent interactions (NCIs) drive the formation of organic cocrystals with diverse structures and tunable optoelectronic properties. This review explores the essential factors governing these properties, highlighting how the sequential nucleation of cocrystals leads to the self‐assembly of organic hierarchical structures (OHSs).
