Here we present such a material synthesized from the electropolymerization of a thienyl pyridazine compound, 1,4-di(thiophen-2-yl)-2H-cyclopenta[<em>d</em>]pyridazine, on a platinum disk electrode from acetonitrile solution. The thienyl pyridazine electropolymer functionalized electrode loses its ability to reversibly oxidize decamethylferrocene, while retaining quasi-reversible oxidation of both ferrocene and acetylferrocene, attributed to their more positive redox potentials. In addition, the thienyl pyridazine electropolymer formed through successive cyclic voltammetric cycles is shown to be comparable to that formed by the method of prolonged applied 1.0 V bias. Electrochemical impedance spectroscopy (EIS) is used <em>in situ</em> to help infer kinetic and mechanistic information of thienyl pyridazine film formation. Finally, it is shown that electropolymerization can be sterically hindered by the presence of a perfluoropyridine group on the thienyl pyridazine monomer at the nitrogen position, showing that electropolymerization can be significantly impacted by changes to the pyridazine center of the monomer.</div></div>","PeriodicalId":22245,"journal":{"name":"Synthetic Metals","volume":"311 ","pages":"Article 117816"},"PeriodicalIF":4.0,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we highlight a promising strategy to overcome these drawbacks consisting to make use of the hollow space within single-walled boron nitride nanotubes (SWBNNTs). As a prototypical system of organic <em>π</em>-conjugated molecules encapsulated in SWBNNTs, we investigate the energetic stability and Raman spectra of a series of oligothiophene molecules (nT) (n = 2, 4, and 6) inside SWBNNTs through a combination of molecular dynamics (MD), density functional theory (DFT), bond polarisability model (BPM), and spectral moments method (SMM). The structural stability of these nanohybrids are explored initially. The optimal SWBNNTs diameters in which the resulting nanohybrids are stable with either one molecule (nT@SWBNNTs) and two encapsulated molecular chains (nT-nT@SWBNNTs) are computed. Then, the computed Raman spectra of the oligothiophenes and SWBNNTs before and after filling are reported. The energetic stability and the possible appearance or not of charge transfer in such nanohybrids are investigated by attentive analysis of the nanoconfinement effect on Raman features of oligothiophenes and SWBNNTs.

Thin films of poly(aniline-co-<em>o</em>-toluidine) (PA-co-POT) were electrodeposited on the surface of carbon steel using cyclic voltammetry in an electrolyte consisting of oxalic acid, aniline and o-toluidine monomers. The mechanical properties of the polymer films were analyzed by a micro-Vickers hardness tester. The corrosion resistance of the polymer films was evaluated by an electrochemical corrosion test and immersion test of the polymer films in a solution containing SRB and 3.5 % NaCl. The results showed that PA-co-POT films have superior SRB corrosion resistance than single polymer films. The corrosion rate of PA-co-POT film was 0.0171 mm/year, and the protection efficiency was 83 % after 14 days of immersion in solution. In addition, due to the antibacterial properties of the PA-co-POT film, the adhesion of bacteria on its surface is significantly reduced, and local corrosion is also effectively inhibited.

P3HTs doped with the p-type molecular dopant 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F₄TCNQ) exhibited distinct nanostructures as the molar dopant ratio (MDR, [F₄TCNQ]/[hexylthiophene]) increased.

At relatively higher doping levels (MDR ≥ 0.05), the doped P3HT films showed large size aggregates with less long range order and resulted in poor transistor performances, while their electrical conductivities gradually increased as the MDR increased.

For this purpose, the solvation effect on chain conformations was used as a probe, assuming that the higher the viscosity, the less mobile the chain will become. The higher rigidity as compared to the previous one was achieved by three ways: replacing the previous <em>ter</em>-pyridine sites by the less bulky <em>di</em>-pyridine ones; increasing the number of complexed lanthanide ions from 20 % to 80 % (molar basis) and inserting double bonds in place of single ones.
