Room temperature ionic liquids (ILs), especially protic ionic liquids (PILs), are used in many areas of the chemical sciences. Ionicity, the extent of proton transfer, is a key parameter which determines many physicochemical properties and in turn the suitability of PILs for various applications. The spectrum of computational chemistry techniques applied to investigate ionic liquids includes cl...

A novel anion templation route has been developed to synthesise two new catenanes, which are observed to selectively complex chloride in protic solvent media.

Physicochemical properties, ionicity, and fragility for protic ionic liquids (PILs) based on the protonation of the extremely fragile molecular liquid decahydroisoquinoline (DHiQ) by various Brønsted acids have been studied. The ionicity was evaluated using the Walden plot diagnostic, while the m-fragility (slope of T(g)-scaled Arrhenius plot at T(g)) was quantitatively measured by the Moynihan...

Hybrid materials, i.e., the organically modified silicates (ORMOSIL) based on zincphthalocyanine (ZnPc) and silica glass matrix were synthesized by sol-gel method using protic solvents (methanol, ethanol, isopropanol, butanol) aprotic solvent (N,N-dimethylformamide; DMF). The effect of an alkaline environment with NaOH addition (a single-stage process) acid–alkaline CH3COOH-NH4OH HCl-NaOH two-s...

Protic ionic liquids have been regarded as promising materials to capture CO2, because they can be easily synthesized with an attractive capacity. In this work, we studied the CO2 absorption mechanism by protic (ILs) composed of diamino cations and azolide anions. Results 1H nuclear magnetic resonance (NMR), 13C NMR, 2-D NMR fourier-transform infrared (FTIR) spectroscopy tests indicated that re...

Foams are attractive platforms for engineering gas–liquid–solid catalytic microreactors with enhanced triphasic contact. In this study, the foaming properties of surface-active AquivionTM perfluorosulfonic acid resin (AquivionTM PFSA) unraveled. Stable aqueous and non-aqueous foams prepared driven by hydrogen bond interactions between PFSA protic solvents (e.g., benzyl alcohol, aniline, water)....

The aim of this work was the design, synthesis, and characterization new chromogenic spirolactone dyes based on a 2-phenyl-1-benzopyrylium (flavylium) backbone for further development thermochromic smart labels. influence electron-donating electron-withdrawing groups five synthesized studied in terms color modification, acid-base behavior properties. By using UV–Vis absorption emission spectros...

The mechanism for the dual emission of 2-(4'-N,N-dimethylaminophenyl)imidazo[4,5-c]pyridine (DMAPIP-c) in protic solvents was investigated by synthesizing and studying its analogues. Theoretical calculations were carried out to corroborate the experimental findings. The deprotonation studies suggest that the enhancement in the TICT emission of anionic forms of DMAPIP-c is limited to a protic en...
