The members of a homologous series of chiral compounds often show inconsistent enantioselectivities when separated on the same chiral stationary phase. The reasons behind this are subject to debate due to the lack of an efficient way to probe the molecular level separation mechanisms on conventional chiral stationary phases. Homochiral metal–organic frameworks (HMOFs) are a family of new porous, crystalline materials that can be used as chiral stationary phases. The regular structures of HMOFs make possible the detailed interrogation of chiral separation mechanisms through molecular modeling. In this report, molecular modeling techniques were used to study the enantioselectivities of a homologous series of chiral compounds in two different HMOFs. We demonstrate that a shift in the adsorption site is one reason for the lack of a correlation between the enantioselectivities of a homologous series of chiral compounds. In addition, we demonstrate that a smooth HMOF pore can help preserve the adsorption site and the separation mechanism, and hence achieve consistent enantioselectivity for a homologous series of chiral compounds.

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.
