“…A range of models have been used to describe IL bulk structure, including ion pairs, [3][4][5][6] hydrogen-bonded networks, [7][8][9][10][11][12][13][14][15][16] ion clusters, [17][18][19] and self-assembled nanoscale structuring. 1,[20][21][22][23][24][25][26][27][28][29] The most appropriate model is strongly related to the type of IL under study, as there are many distinct classes.…”

“…20,30,31 Since then, the structure of ILs has been an intense research area with several reviews on their bulk structure having being written. 7,8,[32][33][34][35] Early molecular dynamics (MD) simulations postulated the formation of nanostructure within several different systems of [Cnmim][X]. 21,[23][24][25] When alkyl chains were sufficiently long the chains were observed to aggregate to form alkyl-chain domains.…”

“…The constituent cations and anions of ILs are commonly strongly asymmetric, flexible, polar, polarizable, and often hydrophobic. 1,2 These amphiphilic properties lead to poorly ordered solids with free energies that favor the liquid over the crystalline state near ambient temperatures. These properties of ILs are also responsible for the great interest in using them for energy applications such as for solar photoelectrochemical cells, lithium batteries, ultracapacitors, safe handling and processing of highly radioactive materials, and dissolution of biomass.…”

“…29 The x-ray experiments measure the coherent x-ray scattering intensity, I coh (q), as a function of scattering vector, q = | q| = (4π/λ) sin(θ ), where 2θ is the scattering angle and λ is the x-ray wavelength. The I coh (q) is corrected in order to calculate the structure function, S(q) 2 , where x i and f i are the atomic concentration and x-ray scattering factor, respectively, for the atomic species i.…”

We report the structure functions obtained from x-ray scattering experiments on a series of four homologous ionic liquids. The ionic liquids are 1-alkyl-1-methylpyrrolidinium cations paired with the bis(trifluoromethylsulfonyl)amide anion, with alkyl chain lengths of n = 4, 6, 8, and 10. The structure functions display two intense diffraction peaks for values of the scattering vector q in the range from 0.6 to 1.5 Å−1 for all samples. Both diffraction peaks shift to lower values of q for increasing temperature. First sharp diffraction peaks are observed in the structure functions for q < 0.5 Å−1 for liquids with n = 6, 8, and 10.

Lab-on-a-chip and miniaturized systems have gained significant popularity motivated by marked differences in material performance at the micro-to-nano-scale realm. However, to fully exploit micro-to-nano-scale chemistry, solvent volatility and lack of reproducibility need to be overcome. Here, we combine the non-volatile and versatile nature of ionic liquids with microcontact printing in an attempt to establish a facile protocol for high throughput fabrication of open microreactors and microfluidics. The micropatterned ionic liquid droplets have been demonstrated as electrochemical cells and reactors for microfabrication of metals and charge transfer complexes, substrates for immobilization of proteins and as membrane-free high-performance amperometric gas sensor arrays. The results suggest that miniaturized ionic liquid systems can be used to solve the problems of solvent volatility and slow mass transport in viscous ionic liquids in lab-on-a-chip devices, thus providing a versatile platform for a diverse number of applications.
