Themed collection Ionic Liquids in the Synthesis, Fabrication, and Utilization of Materials and Devices

This work predicted propagation rates of free radical polymerisation in clusters of ionic liquids: stabilisation of the propagating radical and deactivation of the monomer were found to be the main factors in controlling kinetic rates, allowing for controlled free radical polymerisation in ionic liquids.

Most ionic liquids are not, as frequently asserted, materials of unusual thermal stability. However, it is possible to create ionic liquids which are, through a combination of iterative ion design/synthesis, and thermochemical measurements, coupled with quantum and molecular dynamics calculations.

Increasing energy demands call for new energy storage technologies with high energy density to meet current and future needs.

The application of click reaction (e.g. CuAAC, thiol–X, oxime formation and nucleophilic ring opening) has recently begun to draw attention for efficient and robust synthesis of new functional ionic liquids, requiring minimal purification.

XPS is used to investigate the impact of sulfur containing substituents on the electronic structure of a series of N-based cations, all with a common anion, [NTf₂]⁻. The experimental data is complex and cannot be easily deconstructed, DFT provides critical insight into bonding and electronic structure for each system studied.

Encounter complexes of a frustrated lewis pair are more stable and prevalent in an ionic liquid than in benzene.

An ionic liquid derived highly nitrogen-rich mesoporous carbon supported Au–Pd alloy was found to be an efficient and recyclable catalyst for the Ullmann coupling reaction of various aryl chlorides at room temperature.

A supercapacitor with a piperidinium ionic liquid and an LiTFSI electrolyte operates for 10 000+ cycles at 100 °C.

A lithium battery with excellent performance and thermal stability is realized by using a nanostructured electrode and an ionic liquid.

Li ion transport in ionic liquid is dominated by vehicular transport in net negatively charged clusters even at enhanced salt concentration.

A chloroaluminate inorganic ionic liquid electrolyte can boost the electrochemical activity of a graphitic carbon cathode for rechargeable Al batteries.

A concentrated lithium salt electrolyte utilising the diethylpyrrolidinium cation and bis(fluorosulfonyl)imide anion shows high ionic conductivity and good Li electrochemistry.

Fluorinated ionic liquids rich-nanosegregated behaviour reduces the impact of the addition of water upon the ionic liquids's H-bond acceptance ability.

Sodium ion batteries (SIBs) are widely considered as alternative, sustainable, and cost-effective energy storage devices for large-scale energy storage applications.

Deuteron NMR spectroscopy is a suitable method to study dynamical heterogeneities in protic ionic liquids. In the ²H spectra of the protic ionic liquid [TEA][OTf] we observe anisotropic and isotropic signals at the same time.

Alternating anodic and cathodic current pulses have been applied to a metal powder on an electrode surface to fuse the particles together. It is shown that homogeneous films can be electroformed with different morphologies depending on the size of the powder and the experimental conditions.

Membranes based on supported ionic liquid-like phase (SIILP) systems with tunable properties allowed oil/water separation and reaction/separation integration in biphasic systems.
