Observations of probe dependence of the solvation dynamics in ionic liquids
Literature Information
Jens Breffke, Nikolaus P. Ernsting, Mark Maroncelli
Solvation and rotational dynamics of 4-aminophthalimide (4AP) in four ionic liquids (ILs) are measured using a combination of fluorescence upconversion spectroscopy and time-correlated single photon counting. These data are compared with previously reported data for coumarin 153 (C153) to investigate the probe dependence of solvation dynamics. No fast component (<15 ps) in the fluorescence anisotropy is observed with 4AP. The differences between the solvation response functions of 4AP and C153 are significant in all four ILs, but these differences can be reduced by applying a correction for solute rotation using measured emission anisotropies. Response functions of other probes available in the literature are used to further examine the validity of this correction. The corrected data are also compared to predictions of dielectric continuum models of solvation. By replacing the measured static conductivity of the ILs with an estimated value, such predictions show good agreement with the observed spectral response functions, especially when the anion size is small.

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.
