“…For applications in biology,P EDOT:PSS has some weaknesses, mostly due to its low biofunctionality (PEDOT) and biocompatibility (PSS), being necessary to replace the latter with ab iopolymer. [13] Metallacarboranes, of which cobaltabisdicarbollide, [Co(C 2 B 9 H 11 ) 2 ] À ,d enoted as [COSANE] À ,i st he most researched, are redox-reversible highly stable speciesw ith large possibilities for functionalization. They have been utilized both as components of pendant arms and as doping agentsw ith PPy [4a-d] and in ap rospective PEDOT polymer.…”

Conducting organic polymers (COPs) are made of ac onjugated polymer backbone supporting ac ertain degree of oxidation. These positive charges are compensated by the doping anions that are introduced into the polymer synthesis along with their accompanying cations.I nt his work, the influence of these cations on the stoichiometry and physicochemical properties of the resulting COPs have been investigated, something that has previously been overlooked,b ut, as herep roven, is highly relevant. As the doping anion, metallacarborane [Co(C 2 B 9 H 11 ) 2 ] À was chosen, which acts as at histle.T his anion binds to the accompanying cation with ad istinct strength. If the binding strength is weak, the doping anion is more pronet oc ompensate the positivec hargeo ft he polymer,a nd the opposite is also true. Thus, the ability of the dopinga nion to compensate the positive charges of the polymer can be tuned, and this determines the stoichiometry of the polymer.A st he polymer,P EDOT wass tudied, whereas Cs + ,N a + ,K + ,L i + ,a nd H + as cations.N otably,w itht he [Co(C 2 B 9 H 11 ) 2 ] À anions, these cations are grouped into two sets, Cs + and H + in one and Na + ,K + ,a nd Li + in the second, according to the stoichiometry of the COPs:2 :1 EDOT/[Co(C 2 B 9 H 11 ) 2 ] À for Cs + and H + , and 3:1E DOT/[Co(C 2 B 9 H 11 ) 2 ] À for Na + ,K + ,a nd Li + .T he distinct stoichiometries are manifested in the physicochemical properties of the COPs, namely in the electrochemical response, electronic conductivity,i onic conductivity,a nd capacitance.Supporting information and the ORCID identification number(s) for the author(s) of this articlecan be found under: https://doi.

In this paper, we report an electrochemical material for nicotine detection in aqueous solution by using glassy carbon electrode (GCE) electrodeposited with Nickel(II) phthalocyanine‐tetrasulfonic acid tetrasodium salt (polyNiTSPc) in Tetra n‐bütil ammonium hydroxide (TnBAH) alkaline solution. The detection performance of the polyNiTSPc/GCE and the reaction mechanism of nicotine electro‐oxidation process is investigated using Cyclic Voltammetry (CV) and Square Wave Voltammetry (SWV) techniques in 0.1 M phosphate buffer solution (pH 7.5). The conductivity properties of the bare GCE and polyNiTSPc/GCE were analysed using Electrochemical impedance spectroscopy (EIS). The surface morphology of bare GCE and polyNiTSPc/GCE are characterized by Atomic Force Microscopy (AFM). PolyNiTSPc shows high catalytic activity for the electro‐oxidation of nicotine, with the limit of detection at 146 nM nicotine. PolyNiTSPc/GCE can be used as a biosensor with very low detection limit for nicotine. Electrode process for nicotine oxidation is diffusion controlled, including irreversible one‐electron transfer attributed to the nicotine/nicotine‐Δ1′,(5′)‐iminium ion conversion on the polyNiTSPc coated electrode. Electrochemical measurements indicated that the polyNiTSPc against nicotine plays a similar role as CYP2A6 enzyme which catalyses the intermediate reaction product of nicotine‐cotinine transformation in most mammalian species.

Sulfur-containing polymers and poly(ionic liquid)s are emerging macromolecules with unique properties and applications. This article shows the first integration of these two polymer families, leading to materials with a unique combination of properties. The synthetic strategy toward sulfur-containing poly(ionic liquid)s involves first the copolymerization of elemental sulfur with 4-vinylbenzyl chloride and subsequent quaternization of the alkyl chloride group using N-methyl imidazole. The synthetic pathway is completed by the anion exchange reaction of the poly(sulfur-co-4-vinylbenzyl imidazolium chloride) by a sulphonamide anion. The obtained polymers are fully characterized by NMR, FTIR, SEC, DSC, and TGA. The sulfur poly(ionic liquid)s combine some properties related to its poly(ionic liquid) nature, such as anion-dependent solubility (water vs organic solvents) and high ionic conductivity as well as properties related to its sulfur content, such as redox activity.
