The thermal behavior of I [R = H, Br; X = Br, NTf2; n = 2, 6; m = 1, 4] and II ILs, belonging to two structurally related families with either bromide or Tf2N as counteranion, was analyzed. For bromide mono- I and dicationic ionic liquids II (DILs), thermal gravimetric anal. showed similar decomposition events, with only small gain in stability for a few members of the latter class. Conversely, all Tf2N DILs displayed higher stabilities (up to 34 K) than the corresponding monocations, thus highlighting the different role played by the two counteranions. Mono- and dicationic ILs bearing a reactive group on the imidazolium substituent resulted instead the least stable ILs studied. Differential scanning calorimetry anal. of most of the (D)ILs only showed glass transition temperatures, a behavior in agreement with the broad liquid range of ILs. The impact of the cationic structure and/or of the type of anion on the above-mentioned transition temperatures were studied. The apparent activation energy (Ea) and the fragility index (m) for some (D)ILs had also been obtained. Finally, a few bromide (D)ILs presented peculiar thermal events. In the experiment, the researchers used many compounds, for example, 1,6-Dibromohexane(cas: 629-03-8Synthetic Route of C6H12Br2)
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.Synthetic Route of C6H12Br2
