We report the results of X-ray scattering, physical, and spectroscopic measurements on a series of water-saturated trialkylamine/carboxylic acid mixtures. The results demonstrate the existence of well-defined nanoscale structures in bulk liquid mixtures at specific acid : amine ratios. These structures are analogous to those observed in ionic liquids but are driven by the formation of a hydrogen-bonded network rather than via inter-ion Coulomb forces. The results of the physical components of this study are closely analogous to prior observations on anhydrous, low molecular weight acid/amine mixtures, but this is to our knowledge the first time these observations have been augmented by the use of X-ray scattering. The results therefore bridge the gap between early work on amine/acid mixtures and recent studies of protic and pseudoprotic ionic liquids.

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.
