The autonomous process occurs spontaneously, and it allows obtaining diverse substances, from simple molecules to macromolecules, as well as 1D, 2D, and 3D materials of different natures. Thus, self-assembly is responsible for the formation of a huge variety of substances, such as oligomeric metal complexes [4–9], coordination polymers [10–14], varied (metallo)supramolecular materials [15–22], metal–organic frameworks [23,24], complex materials [25–28], biomaterials [29–31], and nanomaterials [32–36]. Furthermore, they can present amazing properties [37–42], so they are useful in diverse fields [43–50].eng© 2024 by the authors. Licensee MDPI, Basel, Switzerland.
