“…These positive charges are formed during the electropolymerization or p ‐doping at high potentials . This phenomenon is called in the literature as charge trapping . Since the presence of the charges trapped causes a coulombic repulsion between the mobile charges, their presence affects the conductivity value.…”

“…[101] This phenomenon is called in the literature as charge trapping. [146][147][148][149] Since the presence of the charges trapped causes a coulombic repulsion between the mobile charges, their presence affects the conductivity value. Therefore, potentiodynamic in-situ electrochemical-conductance allows to discern between the ndoping process (where conductivity is present) and the reduction of these charges trapped, with the concomitant expulsion of their counter ions (where no conductivity is observed).…”

“…Practical applications of electronically conducting polymers (CP) in LED devices, electrochemical transistors, electrochromic windows, and rechargeable batteries are largely based on the phenomenon of reversible p-and n-doping. [1][2][3][4][5][6] By definition, simple p-doping is the removal of electrons from the p-conjugated polymeric backbone (partial oxidation), which is equivalent to the creation of a cation-radical species. The latter is stabilized both by delocalization within the p-system, and by anion insertion from the solution.…”

“…An important advantage of CP over conventional inorganic ion-insertion cathodes and anodes for rechargeable batteries is that a simple chemical derivatization of the CP structure may lead to a drastic, targeted change of their unique molecular properties. 1 In order to balance the n-and p-doping levels, a series of monomers based on (fluorophenyl) thiophenes has been suggested and tested in experimental cells. [11][12][13] In the present work, we obtained 3-(3,4,5-trifluorophenyl)thiophene by modifying the synthetic procedure reported in ref.…”

“…Each spectrum acquisition was performed under bias potential which was applied before the spectrum acquisition for a time long enough to drive the system into a stationary state. The HOMO-LUMO determination was carried out using the current onset of the stable CV traces [14] using a vacuum level of −4.5 eV for the Standard Hydrogen Electrode (SHE) [15] and a redox potential of 0.69 V vs. SHE for the Fc + /Fc in ACN [16].…”
