Abstract

Pyridine, L-alanine and L-phenylalanine dissolved in the liquid crystalline phases of the lyotropic system CsPFO/water are studied by means of 2H, 13C and 1H NMR. The orientational order parameters of the solutes are determined in a wide temperature range, together with some relevant geometrical parameters. In particular, a prevailing conformation for L-phenylalanine interacting with the micelle is suggested and, for all solutes, convincing representations of their specific interactions with the micelle surface are inferred. From 19F and 13C NMR spectra in the nematic phase, the orientational order parameters for the perfluorooctanoate chain inside the micelles are estimated.

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.
