Binuclear Fe(III) Fused Porphyrin


­Potential Applications
•  Electron-conducting molecular wires
•  Electrocatalysis
•  Non-linear optical materials
•  Supramolecular chemistry

Benefits and Advantages
•  Achieves twice the redox activity seen in mononuclear porphyrin
•  Bimetallic-iron sites
•  Capable of delocalizing electrons across the multimetallic scaffold
•  Can store up to six electrons

Invention Description
Research at Arizona State University has resulted in the synthesis of a novel binuclear Fe(III) fused porphyrin. Ultraviolet-visible spectroscopy confirms the extended electronic structure of this macrocycle. In addition, Fourier transform infrared spectroscopy indicates the Fe centers experience a relatively rigid ligand environment as compared to a structurally related mononuclear complex featuring an 18 π-aromatic porphyrin ligand. X-ray photoelectron and X-ray absorption near edge spectroscopies confirm the presence of Fe(III) centers in the as-prepared resting state. In comparison with the mononuclear porphyrin, electrochemical measurements show there is a doubling of the number of redox events associated with the fused binuclear complex.
