The physicochemical properties (ionic conductivity, viscosity, density, and self-diffusion coefficient) of tri-n-ethylpentylphosphonium bis(trifluoromethanesulfonyl)amide (TEPP-TFSA) ionic liquid were compared with those of tri-n-ethylpentylammonium bis(trifluoromethanesulfonyl)amide (TEPA-TFSA). Compared with the TEPA-TFSA ionic liquid, the density and viscosity of the phosphorus ionic liquid are lower, although the ionic conductivity and self-diffusion coefficient are higher. The molar conductivities were compared for the values obtained by the electrochemical impedance method (electrochemical conductivity) and the calculated from the pulsed-gradient spin-echo nuclear magnetic resonance method (diffusive conductivity). The comparison shows that active ionic ratios of the TEPP-TFSA ionic liquid were smaller than those of the TEPA-TFSA ionic liquid in the whole temperature, regardless of the lower viscosity of the TEPP-TFSA ionic liquid, and results with high precision were obtained using Walden’s law.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
