Catalysing electropolymerization: High-quality polythiophene films for electrochemical sensors by the utilization of fluorine based Lewis acid catalysts

Straightforward Approach for Electrochemical Deposition and Modification of Conductive Polythiophene Thin Films for Bioreceptor Immobilization

“…Various benzoic acid derivatives show a band at around 1370-1380 cm −1 , which is identified as the symmetrical stretching vibrations of COO − groups and can also be found in the SERS spectra of PABA in this work. In addition, a broad band of similar intensity can be found with a maximum at 230 cm −1 , which is associated with oxygen but could not yet be clearly identified [20]. The spectrum of the PABA-modified PTh film contains both the band of ν S (COO − ) as well as the oxygen-associated band, proving the successful binding of PABA to PTh.…”

“…Scanning electron microscope (SEM) pictures of the optimized film in comparison to a film with rough surface topography can be seen in Figure 1. Lately, we also found and published that electropolymerization can be catalyzed, which also grants the films a smoother surface morphology and increases the selectivity of polymerization [19,20].…”

“…16 onward. This peak is produced by the reduction of the polythiophene film (deprotonation phase [42]). The second reduction peak has a broad shape owing to a capacitive component, a graphene-thiophene composite most likely.…”

Spectroscopy, molecular structure, and electropolymerization of Ni(ii) and Cu(ii) complexes containing a thiophene-appending fluorinated Schiff base ligand

“…11,12 An attractive and well-known scaffold is thiophene, 13 which can be electropolymerized at anodic potentials ranging between 1.2 to 1.6 V vs. a saturated calomel electrode (SCE, depending on the experimental conditions). 14 Polythiophenes are especially attractive due to their lightweight, flexibility, structural versatility, and chemical, electrochemical and environmental stability, [15][16][17] exceeding that of polypyrrole or polyaniline monomers. 18 Also, these polymers are highly conductive (100 S cm −1 ) and have thermal and chemical stability.…”
