On the other hand, an increasing interest has been evidenced in the chemistry of corroles and their metallo-derivatives because of their unique photophysical and electrochemical properties . Corroles are analogous to porphyrins but lacking the C20 meso-carbon atom at the core structure, and they have been proposed as suitable compounds in cancer therapy, sensing, organic electronics, and catalysis . In this sense, new synthetic strategies for developing corrolic derivatives have been proposed, mainly substituted at the beta and/or meso positions of the corrolic core. Here, electron-withdrawing meso-substituents appear as an excellent strategy to increase the stability of the macrocycle, in combination with the modulation of the electron density on the core structure of the corresponding derivatives . Alternatively, the binding of metal cations in the central cavity has also been explored; Fe(IV) and Cu(III) corrole complexes have been recognized as exciting metallo-derivatives, where the corrolato moiety acts as a non-innocent ligand. In the particular case of Cu-corroles, this definition implies a rearrangement of the electronic structure of the π-extended macrocycle upon metalation.
