Ferrocene- and Biferrocene-Containing Macrocycles towards Single-Molecule Electronics

Cyclic multiredox centered systems are currently of great interest, with new compounds being reported and developments made in understanding their behavior. Efficient, elegant, and high-yielding (for macrocyclic species) synthetic routes to two novel alkynyl-conjugated multiple ferrocene- and biferrocene-containing cyclic compounds are presented. The electronic interactions between the individual ferrocene units have been investigated through electrochemistry, spectroelectrochemistry, density functional theory (DFT), and crystallography to understand the effect of cyclization on the electronic properties and structure. Setting the ferrocene: Strategies for the synthesis and incorporation of ferrocenyl and biferrocenyl units within small alkynyl-linked rings are reported. These systems were characterized by in-depth cyclic voltammetry, spectroelectrochemistry, DFT, and X-ray crystallography.
