Published: April 2012

The kinetics and mechanism of the proton reduction reaction in the room temperature ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C(2)mim][NTf(2)]) was studied at gold, molybdenum, nickel, titanium and platinum electrodes. Significant differences in electrochemical rate constants were observed between the different metals and with the corresponding processes in aqueous solution. The hydrogen evolution mechanism was consistent at all five metals in the ionic liquid, in stark contrast to the known behaviour in aqueous systems.

This review paper provides an inclusive overview of the intricate interactions amid ionic liquids (ILs) and essential biomacromolecules, mainly Hemoglobin (Hb), Bovine Serum Albumin (BSA), Human Serum Albumin (HSA), and Calf Thymus-DNA (CT-DNA). ILs have recently become a topic of great attention because of their inimitable physicochemical properties and potential uses in different fields. The review systematically explores the binding mechanisms, thermodynamics, and structural changes induced by ILs on Hb, BSA, HSA, and CT-DNA using spectroscopic, thermodynamic, and computational techniques.

A pair of axially chiral thermally activated delayed fluorescent (TADF) enantiomers, R-TCBN-ImEtPF6 and S-TCBN-ImEtPF6, with intrinsic ionic characteristics were efficiently synthesized by introducing imidazolium hexafluorophosphate to chiral TADF unit. The TADF imidazolium salts exhibited a high photoluminescence quantum yield (PLQY) of up to 92%, a small singlet-triplet energy gap (∆EST) of 0.04 eV, as well as reversible redox properties.

Carbon dioxide capture has attracted worldwide attention because CO emissions cause global warming and exacerbate climate change. Ionic liquids (ILs) have good application prospects in carbon capture due to their excellent properties, which provide a new chance to develop efficient and reversible carbon capture systems. This paper reviews the recent progress in CO chemical absorption by ILs, such as N-site, O-site, C-site, and multi-site functionalized ILs.

This study proposes fluorenylmethoxycarbonyl (Fmoc)-protected single amino acids (Fmoc-AAs) as a minimalistic model system to investigate liquid-liquid phase separation (LLPS) and the elusive liquid-to-solid transition of condensates. We demonstrated that Fmoc-AAs exhibit LLPS depending on the pH and ionic strength, primarily driven by hydrophobic interactions. Systematic examination of the conditions under which each Fmoc-AA undergoes LLPS revealed distinct residue-dependent trends in the critical concentrations and phase behavior.

Androgenic alopecia (AGA), the most prevalent type of progressive hair loss, currently lacks an effective topical treatment regimen. In this study, we synthesized an ionic liquid (IL) to co-solubilize minoxidil (MXD) and finasteride (FIN) and subsequently formulated them into an in situ thermosensitive ionic liquid/cyclodextrin/poloxamer hydrogel (ICPG), termed M + F@ICPG. M + F@ICPG was developed for the transdermal co-delivery of these two drugs, aiming to provide a multipath therapeutic approach for AGA while avoiding the adverse effects commonly associated with oral FIN and topical MXD tincture.
