Despite extensive reports on highly efficient perovskite light-emitting diodes, rules governing the design of suitable two-dimensional (2D) templating cation to facilitate formation optimal emitter landscape for energy cascade remain largely elusive. With factors such as structure, size, functionalization, and charge capable influencing distribution multidimensional phases, importance 2D in det...

A systematic study of the interactions between water and alkyl methyl imidazolium chloride ionic liquids at 298.2 K, based on activity coefficients estimated from water activity measurements in the entire solubility range, is presented. The results show that the activity coefficients of water in the studied ILs are controlled by the hydrophilicity of the cation and the cation-anion interaction....

Aqueous biphasic systems (ABS) using ionic liquids (ILs) offer an alternative approach for the extraction, recovery, and purification of biomolecules through their partitioning between two aqueous liquid phases. In this work, the ability of a wide range of ILs to form ABS with aqueous solutions of Na2 CO3 was evaluated. The ABS formed by IL + water + Na2 CO3 were determined at 25°C, and the res...

Herein we describe the synthesis of gold nanoparticles (Au-NPs) in presence of sulphonated imidazolium salts [1,3-bis(2,6-diisopropyl-4-sodiumsulfonatophenyl)imidazolium (L1), 1-mesityl-3-(3-sulfonatopropyl)imidazolium (L2) and 1-(3-sulfonatopropyl)imidazolium (L3)] in water and in a confinement environment created by reverse micelles (RMs). The Au-NPs were characterized-with an excellent agree...

Experimental and simulation results of solvation dynamics in ionic liquids have so far been explained in terms of translational motion of the ions constituting the ionic liquids under investigation. A recent theoretical study [Kashyap & Biswas, J Phys Chem B, 114 (2010) 254] has indicated that while translational motion of the constituent ions is indeed responsible for Stokes’ shift dynamics of...

The title compound, 6C5H9N2 (+)·3SiF6 (2-)·CH3OH, (I), was prepared by recrystallization of the crude salt from methanol along with solvent-free 2C5H9N2 (+)·SiF6 (2-) (II). Crystals of these solvatomorphs can be separated manually. The solvate (I) crystallizes in a rare hexa-gonal space group P6/mcc. Its asymmetric unit comprises one half of an imidazolium cation bis-ected by the crystallograph...

Ionic liquids (ILs) are excellent solvents for cellulose, but the dissolution mechanism is not deeply understood. In present study, cellobiose was used as a model of and imidazolium halide-based ILs with same cation 1-butyl-3-methylimidazolium (Bmim+) including BmimCl, BmimBr, BmimI were solvents. The interaction between analyzed by carbon-13 nuclear magnetic resonance (13C NMR). results showed...

Macrocycles based on neutral calixarenes and calixpyrroles have been extensively explored for ion binding, molecular assembly and related applications. Given that only these two types of calix compounds and their analogs are available, the introduction of new forms of widely usable calix macrocycles is an outstanding challenge. Here we report the quadruply/quintuply charged imidazole-based homo...

Synthesis of imidazolium carboxylate compounds was efficiently achieved by electrochemical reduction of imidazolium precursors under very mild conditions.
