From Molecular Complexes to Functional Frameworks: A Journey through Noncovalent Interactions in Coordination Assemblies and Organic Crystals

Coordination chemistry is one of the most diverse fields in chemistry. Starting from the unlimited combinations of metals and ligands, a large variety of structures with different coordination modes and geometries can be formed, giving rise to distinct electronic properties that can be harnessed for numerous applications. In particular, noncovalent interactions play a critical role in driving the formation of self-assemblies and supramolecular structures. This account chronicles the author's scientific journey guided by the exploration of noncovalent interactions, moving from the structural and photophysical studies of transition metal complexes to their self-assemblies and, more recently, supramolecular frameworks and organic crystals. These efforts in molecular design and engineering may provide new insights into the future development of functional materials for energy and environmental applications, thereby contributing to key challenges in global sustainability.
