Supramolecular Chemistry of Metalloporphyrins

The supramolecular architectures where the key unit is metalloporphyrins, a most prevalent tetrapyrrolic macrocycle, is reviewed. The two sections of the study includes the design and structure of supramolecular systems and applications of porphyrin supramolecular complexes. The self-assembly of rotaxane and pseudorotaxane systems with a ruthenium carbonyl metalloporphyrin stopper unit is achieved with the support of the pyridyl groups as axial coordination ligands. The porphyrin nanoparticles, held together by hydrophobic and π-stacking effects, can be considered as self-organized systems that are governed by supramolecular chemistry principles. Work is conducted for the incorporation of porphyrins into larger complex and functional systems and for the encapsulation of porphyrins inside self-assembled coordination cages.
