Macrocyclic Ligands

The salen ligand is the parent compound for the Jacobsen catalyst. Most metals form stable complexes with this tetradentate ligand.

Transition metal complexes of the phthalocyanine ligand are thermally very stable (~500^oC) and colorful, used as pigments and laser dyes

Porphine (corrole) complexes are used as models for chlorophyll, heme and cytochrome systems
