Imidazolium poly cation

However, for analysis of conducting polymers grown in ionic liquids the spectra may be complicated by the presence of elements common to both polymer and growth medium. For example, poly(pyrrole) grown in an imidazolium NTf2 ionic liquid will give peaks in the N Is core level spectra from the imidazolium cation... 

Bazureau et al. reported the synthesis of poly(ethyleneglycol) functionalized -ionic liquid phases as functionalized ionic liquids which are promising tools for synthetic applications in ionic-phase combinatorial chemistry [97], Moreover, several research groups have described ionic liquids with imidazolium cations carrying amino functionality. Davis et al. [98] reported for the first time a functionalized ionic liquid with NH2 group, n-propylamine-3-butylimidazohum tetrafluoroborate 18, for capturing C02 (Scheme 17). 

More recently, Tigelaar et al. have developed an alternative polymer membrane to Nafion that contains rigid sulfonated aromatic backbones linked with diamine-terminated poly-(ethylene oxide) (PEO) oligomers. This polymer was developed to increase the amount of ionic liquid in the membrane, where in Nafion, the perfiuorinated nature was thought to be reducing the uptake. The polymer membranes were soaked with a 1 1 mixture of a PIL and water, where the PILs trialed contained the imidazolium cation with either sulfate, triflate, or TFSI anions. The highest conductivity obtained with these polymer membranes was 50 mS/cm at 150 °C with imidazolium—CF3SO3H. ... 

Environmentally friend and electrochemically stable waterproof ionic liquids like imidazolium cations with stable anions were also used. It is known that, unlike highly polar media, a hydrophobic medium facilitates the deposition of uniform well-adherent thick films. For example, the ionic liquid used to synthesize poly(3,4-ethylenedioxythiophene) (PEDOT) films leads to the formation of randomly oriented nanofibers and particles confined to submicrometer-sized domains in the film microstructure [229].
