“…The difference between N2-substituted 29 and N1-substituted 30 was even more dramatic when thiophene was the donor group. 58 Neither of the N1-substituted polymers showed tendency for n-type doping in the working potential range due to the change in the effective conjugation length of acceptor unit which hindered the negative charge carrier formation on polymer backbone.…”

Benzotriazole (BTz) containing polymers have recently emerged in organic electronic applications and they are increasingly attracting a great deal of attention. These polymers are reviewed from a general perspective in terms of their potential use in three main fields, electrochromics (ECs), organic solar cells (OSCs) and organic light emitting diodes (OLEDs). In order to have a better insight into the properties of these polymers, they were compared with similar polymers. Good solubility, optical and electronic properties and synthetic availability make them multipurpose materials. They combine many desired properties in polymers and their use in different device applications is examined in detail.

“…Due to their advantages of low cost synthesis, easy derivatization and impeccable integration into many electronic devices, p-conjugated conducting polymers (CPs) have attracted great attention over the last decade. CPs have been frequently used in a wide range of industrial applications including organic light emitting diodes (OLEDs), 1,2 field effect transistors (FETs), 3,4 electrochromic devices, [5][6][7] sensors, 8,9 organic photovoltaics (OPVs), [10][11][12] and supercapacitors (SCs). [13][14][15][16] Particularly, the use of CPs as electrochromic materials has been widely investigated since p-conjugated conducting polymers exhibit reversible and steady color changes at low potentials, high optical contrast in visible and near infra-red (NIR) regions and have high coloriation efficiency and fast switching times.…”

“…Since previous studies showed that triazole enhances the proton conductivity with respect to imidazole, it is expected that benzotriazole also presents higher proton conductivity than benzimidazole. Also, the presence of a pendant group bonded to a nitrogen atom of benzotriazole ring create two N‐1 and N‐2 regioisomers, which present different optical and electrochemical behavior . Moreover, small structural variations at the monomers should be considered since they can fine‐tune the electron and proton conductivity properties of the resulting materials.…”

INTRODUCTIONIn an energy scenario that increasingly demands cleaner and more efficient energy sources, fuel cells are considered promising electrochemical devices since they can provide electric energy with high efficiency and low environmental impact, converting the energy stored in fuels with zero pollution levels. The proton exchange membrane fuel cells (PEMFC) are considered one of the most promising sources among the various kinds of existing fuel cells due to their high power density and high power-to-weight ratio. One of the drawbacks of current cells is related to the electrolytes currently in use, limiting their use to temperatures below 100°C when operating under water-assisted proton conduction.The temperature operation above 100°C could increase the performance of PEMFC due to a faster electrode reaction without CO poisoning of the Pt electrocatalyst, easier heating, and high energy efficiency [1][2][3][4][5][6][7][8].The proton exchange membrane is a key component for the operation of PEMFC. During recent years, the study of membrane materials have been focused in obtaining high proton conductivity, low electrical conductivity, low permeability to fuel and oxidant, good chemical and thermal stabilities, good mechanical properties, and low cost [1][2][3][4][5][6][7][8]. 236
