The modulation of solid-state supramolecular assemblies at room temperature is still challenging even though it potentially has very important application prospects. Herein, based on the possibility of overall conformational changes in double-decker phthalocyanine, the room temperature chiral reorganization of solid-state assemblies was investigated. LS (Langmuir–Schaefer) films of achiral double-decker cerium phthalocyanine were fabricated via air–water interfacial assembly and the dependence of supramolecular chirality on the assembly of the achiral double-decker molecules was identified. Interestingly, the corresponding supramolecular chirality in the solid-state can be reorganized with amplification of the Cotton effect and formation of helical nanostructures upon storage at room temperature and atmospheric pressure. These results open new perspectives for the regulation of supramolecular assemblies.

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.
