“…From the CV curves of 2 and 2 − H 2 PO 4 − , the reversibility of 2 is better than that of 2 − H 2 PO 4 − , but the trend is the opposite for α n α , which can be explained by that in the sample of 2 , where the potential scan rate did not reach below zero and adsorption happened in the electrode surface which impeded the electron exchange. In the sample of 2 , αn α of the reduction peak is larger than that of the oxidation peak, which is in accordance with the usual cases − because of the relative instability of the oxidation state. However, from the sample of 2 − H 2 PO 4 − , we discovered that the addition of H 2 PO 4 − can stabilize the oxidation state because of their combination.…”

A novel ferrocenyl anion receptor N, N, N, N-(dimethyl, ethyl, ferrocenecarboxylic amidodimethylene) ammonium fluoborate 2 with multiple binding sites was synthesized. Its anion recognition behaviors were investigated by CV, 1H NMR and UV-vis spectrum. It was found that the combination of two interactions enforced the anion binding ability and the binding selectivity of 2 to phosphate anion. The effects of scan rate on the CV curves of 2 with phosphate were also investigated. In different scan rate, the CV curves kept stable which indicated the strong binding between 2 and phosphate. According to relationships of peak potential, peak currents and scan rate of 2 binding with phosphate, the kinetic parameters of electrode process such as diffusion coefficient Dapp, surface transfer coefficient alphan alpha, and standard rate constant k0 were calculated.

“…[120] Linear dendritic diblock copolymers were synthesized by grafting living PFS onto the benzyl chloride group of first-or second-generation poly(benzyl ether) dendrons. [121] Polyferrocenylphenylphosphine (PFP) block copolymers (PFP-b-PDMS, PFP-b-PFS, PS-b-PFP, and PI-b-PFP) were also prepared by sequential living anionic polymerization. [122] The organometallic block contains coordinating atoms suitable for further functionalization.…”

The study of metallopolymers has blossomed into a mature field over the last few decades. Especially, polyferrocenylsilane (PFS) chemistry has taken a tremendous leap and continues to raise intense interest. Since the discovery of thermal ring-opening polymerization (ROP) of sila[1]ferrocenophanes, PFSs have been also accessed by anionic, cationic, transition-metal-catalyzed, and photolytic anionic ROP methodologies. A plethora of synthetic strategies have been devised, enabling access to a wide variety of copolymers, polyelectrolytes, and nanostructured materials. The distinctive physical properties and functions of many PFS-based polymers have been explored, leading to their apt exploitation in technical applications. Therefore, it is conceivable that PFS-related platforms might be indispensable nano-objects in the near future, as they stand on the verge of a new generation of sophisticated materials.

“…As we know, the electrochemical behaviors are influenced by many factors, such as scan rate, electrolyte concentration and redox center concentration. − However, in the anion recognition of ferrocenyl anion receptors by electrochemical method reported, no one has considered these factors.…”

A series of ferrocene modified hyperbranched polyethers HBPO-Fc with different ferrocene content were obtained by cation ring-opening polymerization followed by esterification. Electrochemical behaviors of HBPO-Fc were investigated by cyclic voltammetry (CV) and the influence of ferrocene content of HBPO-Fc, scan rate, solvent and electrolyte concentration on the electrochemical behaviors of HBPO-Fc were discussed, and the dynamic parameters in electrode processes were calculated. Anion recognition of HBPO-Fc was studied by CV and UV−vis. The binding capacities of HBPO-Fc to different anions were compared, and the binding capacities of HBPO-Fc with different ferrocene content were also discussed. Finally, binding models of HBPO-Fc to anions were proposed.
