The Periodic Table of Metallocorrolates has been widely expanded in recent years, including also main group elements. Among them, phosphorus complexes of corrole have been of particular interest, since these compounds can be easily prepared in good yields, are stable, and show unusual optical properties. For these reasons, phosphorus corroles represent a class of interesting compounds to be exploited in the field of material science or for biomedical investigations and the definition of synthetic pathways for their functionalization is an important step to optimize their properties for various applications.
We have recently developed different pathway for the selective introduction of different substituents in the peripheral positions of phosphorus triarylcorrole complexes. The characterization of such a complexes showed some peculiar properties, such as for example an unusual ruffled geometry of the corrole core, a conformation that has not been considered possible for such a macrocycle.
