On the formation of a protic ionic liquid in nature.
The practical utility of ionic liquids (ILs) makes the absence (heretofore) of reported examples from nature quite puzzling, given the facility with which nature produces many other types of exotic but utilitarian substances. In that vein, we report here the identification and characterization of a naturally occurring protic IL. It can be formed during confrontations between the ants S. invicta...
متن کاملSoluble, folded and active subtilisin in a protic ionic liquid.
The activity of proteases chymotrypsin and subtilisin dissolved in a range of protic hydroxylalkylammonium ionic liquids was tested against the model substrate APEE (N-acetyl-L-phenylalanine ethyl ester); activity was only observed for subtilisin in diethanolammonium chloride (DEA Cl), while chymotrypsin was not active in any PIL tested.
متن کاملLyotropic liquid crystal phases of phytantriol in a protic ionic liquid with fluorous anion.
The phase behaviour of phytantriol in the protic ionic liquid (PIL) 1-methylimidazolium pentadecafluorooctanoate (MImOF) and four different MImOF-water compositions was investigated by small- and wide-angle X-ray scattering (SAXS/WAXS), cross polarised optical microscopy (CPOM) and infrared spectroscopy (IR). MImOF is a distinct protic ionic liquid in that it contains a fluorocarbon anion and a...
متن کاملCharacterization of the phase behaviour of a novel polymerizable lyotropic ionic liquid crystal.
The development of new polymerizable lyotropic liquid crystals (LLCs) utilizing charged amphiphilic molecules such as those based on long chain imidazolium compounds, is a relatively new design direction for producing robust membranes with controllable nano-structures. Here we have developed a novel polymerizable ionic liquid based LLC, 1-hexadecyl-3-methylimidazolium acrylate (C16mimAcr), wher...
متن کاملOn the Use of a Protic Ionic Liquid with a Novel Cation To Study Anion Basicity.
The need for reliable means of ordering and quantifying the Lewis basicity of anions is discussed and the currently available methods are reviewed. Concluding that there is need for a simple impurity-insensitive tool, we have sought, and here describe, a new method using NMR spectroscopy of a weak base, a substituted urea, 1,3-dimethyl-2-imidazolidinone (DMI), as it is protonated by Brønsted ac...
