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.
