Molecular self-assembly provides limitless possibilities to obtain stable and structurally well-defined supramolecules with different physicochemical properties than those of precursor building blocks. From all supramolecular interactions, strong and directional coordination-driven self-assembly allows a fine control over the rational design of two- and three-dimensional architectures with multiple potential applications. The preparation of cutting-edge metallo-supramolecular assemblies based on phthalocyanines, subphthalocyanines and BODIPYs is herein described. These ensembles have been applied for different purposes: i) as molecular receptors showing electronic interactions between the chromophore panels of the host and electroactive guests such as fullerenes and perylenediimides; ii) as hollow molecular containers able to influence a chemical reaction by providing an isolated cavity of particular size and shape, demonstrating, for example, the ability to induce unprecedented photoredox reaction with guest fullerenes, triggered by the porphyrinoid excited state; and iii) as metallosupramolecular amphiphilic systems, able to yield nanostructures via self-organization in aqueous media.
