A solid-state solar cell was assembled with an ionic liquid—l-ethyl-3-methylimidazolium bis(trifluoromethanesulfone)amide (EMITFSA) containing 0.2 M lithium bis(trifluoromethanesulfone)amide and 0.2 M 4-tert-butylpyridine—as the electrolyte and Au or Pt sputtered film as the cathode.51,52 The in situ PEP of polypyrrole and PEDOT allows efficient hole transport between the ruthenium dye and the hole conducting polymer, which was facilitated by the improved electronic interaction of the HOMO of the ruthenium dye and the conduction band of the hole transport material. The best photovoltaic result ( 7p=0.62 %, 7SC=104 pA/cm2, FOC=0.716 V, and FF=0.78) was obtained from the ruthenium dye 5 with polypyrrole as the hole transport layer and the carbon-based counterelectrode under 10 mW/cm2 illumination. The use of carbon-based materials has improved the electric connectivity between the hole transport layer and the electrode.51...

The monomer must be soluble in the ionic liquid at adequate concentrations. Indeed, the solubility of some monomers may be improved using an ionic liquid synthesis of poly(terthiophene) is often hampered by the poor solubility of the monomer, but terthiophene can be dissolved in l-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)amide, [C2mim][NTf2] or N,N-butylmethylpyrrolidi-nium bis(trifluoromethanesulfonyl)amide, [C4mpyr] [NTf2], at concentrations up to 0.05 M [27]. 

If we perform the same experiment with ultrapure l-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([EMIM] TFSA), we do not see the same restructuring with the in situ STM, although MacFarlane describes that it is the anion which is subject to irreversible breakdown in this potential regime. As described by MacFarlane el al. [8] the reduction of TSFA weakens one of the N-S bonds leading to its cleavage ...

Other hydrolases have been studied in ionic liquid media such as Penicillin G acilase (PGA) [2]. Stability studies on this enzyme have been carried out in organic solvents as well as in ionic liquids. The enzyme deactivation was practically instantaneous in toluene and dichloromethane, and only measurable stability was in 2-propanol. The stability of PGA in ILs was notably improved with respect to 2-propanol. A half-life time of 23 h was obtained in l-ethyl-3-methylimidazolium bis((trifluoromethyl)sulphonyl imide ([emim ][TfNj ]) which was about 2000-fold higher than that in 2-propanol.

Studies of capacitance of negatively charged electrodes based on AC and aero/cryo/xerogel carbon in two ILs with the same anion and other cations with an almost similar size, that is, l-ethyl-3-methylimidazolium bis (trifluoromethanesulfonyl) imide (EMITFSI) and Af-butyl-A-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PYR14TFSI) ILs were made (Fig. 27.10).

Vibrational cooling rates in room temperature ionic liquids were measured with picosecond time-resolved Raman spectroscopy [63]. The 1570-cm Raman band of the first excited singlet (Sj) state of frans-stilbene was used. The recorded vibrational cooling rates in l-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (emimTf2N) and l-butyl-3-methylimidazolium bis(trifluoromethylsu]fonyl)imide (bmimTf2N) were close to those in ordinary molecular solvents despite a large difference in thermal diffusivity.
