The peroxidase-like catalytic activity of ferrocene and its application in the biomimetic synthesis of microsphere polyaniline

Abstract

Ferrocene can be used as a peroxidase mimic to catalyze 3,3′,5,5′-tetramethylbenzidine or aniline oxidation in the presence of H2O2.

Redox- and pH-Responsive Polymersomes with Ferrocene Moieties Exhibiting Peroxidase-like, Chemoenzymatic Activity and H2O2-Responsive Release Behavior

“…For some nanoparticles, the onset of microphase separation becomes visible due to the presence of ferrocene units in the hydrophobic block. The membrane thickness is characteristic of the bilayer membrane in polymersomes, prepared by RAFT polymerization, confirming the general formation of the desired polymeric vesicles . Additionally, also vesicle diameters for F c 1B Psomes could be determined by SEM measurements, but with larger diameters (⌀ 142 ± 25 nm; Figure ).…”

Electrodeposition of Three‐Dimensional Network Nanostructure PEDOT/PANI for Simultaneous Voltammetric Detection of Ascorbic Acid, Dopamine and Uric Acid

“…For PANI, The bands at 1492 cm –1 and 1571 cm −1 are due to the absorb vibration of C=C of benzene structure and C−C of quinone rings, respectively . The band around at 1300 cm –1 and 1148 cm –1 correspond to C−N stretching near the quinone rings and the stretching of NH + in doped PANI, respectively; The bands at 825 cm –1 and 740 cm –1 are belong to the aromatic C−H bending in the 1,4‐disubstituted aromatic ring . It can been revealed that PANI film has been successfully coated on the surface of PEDOT, evidenced by the arising of peak around at 1300 cm –1 (proving of the existence of element N in PANI) in the FT‐IR spectra of PEDOT/PANI.…”

A Comparative Study of Biomimetic Synthesis of EDOT-Pyrrole and EDOT-Aniline Copolymers by Peroxidase-like Catalysts: Towards Tunable Semiconductive Organic Materials

“…The reaction was carried out in a pH range between 1 and 4. The spectroscopic characteristics were, like the PANI, obtained enzymatically, however, the electrical conductivity decreased Wang Q. et al (2018) . Our group has also contributed to the biomimetic synthesis field using catalyst supports ( Tierrablanca et al, 2010 ).…”

“…reported the biomimetic synthesis of PANI using ferrocene, a sandwich-type metallocene widely used in organometallic chemistry. To our knowledge, this investigation was the first reporting ferrocene-based enzymomimetic polymerization, leading to a new pathway for the synthesis of CSP Wang Q. et al (2018) .…”
