Benzimidazole dicationic ionic liquids (BDILs) have not yet been widely explored in spite of their potential. Therefore, two structurally related families of BDILs, paired with either bromide or bistriflimide anions and bearing alkyl spacers ranging from C3 to C6, have been prepared Their thermal properties have been studied by thermogravimetric anal. (TGA) and differential scanning calorimetry (DSC), while their elec. properties have been assessed by cyclic voltammetry (CV). TG anal. confirmed the higher stability of the bistriflimide BDILs over the bromide BDILs, with minor variation within the two families. Conversely, DSC and CV allowed for ascertaining the role played by the spacer length. In particular, the thermal behavior changed dramatically among the members of the bistriflimide family, and all three possible thermal behavior types of ILs were observed Furthermore, cyclic voltammetry showed different electrochem. window (C3(C1BenzIm)2/2Tf2N < C4(C1BenzIm)2/2Tf2N, C5(C1BenzIm)2/2Tf2N < C6(C1BenzIm)2/2Tf2N) as well as a reduction peak potential, shape, and intensity as a function of the spacer length. The results obtained highlight the benefit of accessing a more structurally diverse pool of compounds offered by dicationic ILs when compared to the parent monocationic ILs. In particular, gains are to be found in the ease of fine-tuning their properties, which translates in facilitating further investigations toward BDILs as designer solvents and catalysts. The experimental process involved the reaction of 1,6-Dibromohexane(cas: 629-03-8Recommanded Product: 629-03-8)
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of solvent processable and conductive polyfluorene ionomers for alkaline fuel cell applications; synthesis of cross-linkable regioregular poly(3-(5-hexenyl)thiophene) (P3HNT) for stabilizing the film morphology in polymer photovoltaic cells.Recommanded Product: 629-03-8
