“…Our previous work has proved that boron trifluoride diethyl etherate (BFEE) is very suitable for electropolymerization of high oxidation potential monomers, which could be used as both the solvent and the supporting electrolyte. 23,24 And the polymer films obtained from BFEE were flexible and shiny. In other word, the electrochemical method for preparing carbazolebased CPPs in BFEE will discover new properties of CPPs that will expand the application of these materials.…”

Poly(2,7-bis(carbazol-9-yl)-9,9-dimethylfluorene) (PBCMF) polymer with porous structure was fabricated, and its electropolymerization was studied comparatively in dichloromethane (CH 2 Cl 2 ) systems in the presence of different contents of boron trifluoride diethyl etherate (BFEE). When adding BFEE in CH 2 Cl 2 solution, the oxidation potential of BCMF could be decreased obviously. When the content of BFEE increased to 40%, BCMF was oxidized at 0.47 V, while it was oxidized at 1.07 V in pure CH 2 Cl 2 solution. A series of experiments showed that the polymer PBCMF films could be easily obtained in CH 2 Cl 2 -BFEE systems, and films obtained from the 40 vol% BFEE system showed best electrochemical behavior and best fluorescence property. Fourier transform infrared spectra and UV-Vis proved the longer conjugated chains of polymers. And scanning electron microscopy images of polymer films showed that all these polymer films made from BFEE systems had a good porous structure.

“…A partir de então, uma série de filmes poliméricos tem sido sintetizados eletroquimicamente. Os motivos que fazem essa técnica ser amplamente empregada em diversas áreas podem ser resumidos em: controle da espessura do filme formado, onde é possível a obtenção de filmes muito finos; alta adesão a superfície (SAIKRITHIKA et al, 2020); possibilidade de recobrimentos de diferentes geometrias, como por exemplo, sobre nanotubos de carbono (DI VONA e KNAUTH, 2020); obtenção de materiais flexíveis; além de ser um processo rápido, simples e econômico (CHAI et al, 2019).…”

Electrochemical biosensors are versatile tools for clinical diagnosis, because among so many advantages, they have good sensitivity and selectivity and low response times. The use of conducting polymers as a matrix for immobilization of biomolecules contributes to the biocompatibility of biosensors, as there is exposure of functional groups that provide a favorable microenvironment. The objective of this work was the preparation and characterization of a new polymeric material for application in biosensors, the copolymer derived from the monomers 4-aminophenol and aniline, named as poly(aniline-co-4aminophenol) -4-PANAP. The copolymer was electropolymerized on the surface of graphite electrodes, applying cyclical potential scans in an acid medium containing the comonomer mixture. The results of electrochemical, morphological and structural characterization indicated the formation of a new material with hybrid characteristics between poly(4-aminophenol) (P4AP) and polyaniline (PANI). 4-PANAP showed redox peaks in the P4AP region with charge density similar to PANI, with an intermediate behavior between the two against electron transfer. The morphology of 4-PANAP resulted in forms of interconnected fibers, different from the globular PANI and stretched fibers of P4AP. Infrared spectra reveal that both characteristic functional groups of P4AP and PANI remain in 4-PANAP. The application in biosensors was evaluated against the development of an electrochemical immunosensor to detect the thyroid hormone 3,5,3′-triiodothyronine (T3). The study of the immunosensor for T3 allowed the evaluation of the best conditions for electrosynthesis of the copolymer against the detection of T3, which was the electropolymerization with an equimolar monomeric mixture (1:1), in the potential range of -0.1 to +1, 2 V at 50 mV s -1 . From the construction of the analytical curve, a linear relationship between the anodic current and the T3 concentration range was reached, in the working range of 0.2 to 8.8 ρg mL −1 , with a detection limit of 0.60 pg mL −1 and a limit of quantification of 1.80 pg mL −1 . The proposed platform kept 90% of the analytical signal after a period of 60 days, whose results were promising for real applications, achieving success in the performance of the platform.
