International audience; Six- and seven-membered cyclic hydroxamic acids are found as terminal binding units in different families of siderophores, including exochelins and mycobactins. The simplest models of these preorganized chelating ligands were

Photoinduced Electron vs. Concerted Proton Electron Transfer Pathways in SnIV (l-Tryptophanato)2 Porphyrin Conjugates

Autor: Nicola Demitri, Elisabetta Iengo, Mirco Natali, Agnese Amati

Aromatic amino acids such as l-tyrosine and l-tryptophan are deployed in natural systems to mediate electron transfer (ET) reactions. While tyrosine oxidation is always coupled to deprotonation (proton-coupled electron-transfer, PCET), both ET-only a

Proton-coupled electron transfer (PCET) plays a key role in many biological processes, and a thorough comprehension of its subtle mechanistic complexity requires the synthesis and characterization of suitable artificial systems capable of mimicking t

Sn(IV) Multiporphyrin Arrays as Tunable Photoactive Systems

Autor: Maria Teresa Indelli, Mirco Natali, Paolo Cavigli, Elisabetta Iengo, Agnese Amati, Nicola Demitri

A series of four arrays made of a central Sn(IV) porphyrin as scaffold axially connected, via carboxylate functions, to two free-base porphyrins has been prepared and fully characterized. Three arrays in the series feature the same free-base unit and

Formation of a long-lived radical pair in a Sn(iv) porphyrin-di(l-tyrosinato) conjugate driven by proton-coupled electron-transfer

Autor: Elisabetta Iengo, Agnese Amati, Mirco Natali, Nicola Demitri

The novel conjugate 1, featuring two l-tyrosinato residues axially coordinated to the tin centre of a Sn(iv)- tetraphenylporphyrin, is reported as the first example of a supramolecular dyad for photochemical PCET. It is noteworthy that the excitation
