要旨

An azobenzene liquid-crystalline compound possessing two chiral centres at both peripheral ends of the molecular structure exhibits electric-field-induced birefringence in the isotropic liquid phase, which was found to be attributable to the stabilization of the liquid-crystalline organization by the emergence of the polar ferroelectric molecular ordering. The optically isotropic texture changes into the homogeneous birefringent texture by the application of the in-plane electric field, which is a new type of switching mode applicable for the liquid crystal displays. The resulting birefringence can be erased by the irradiation of UV light, due to the photoinduced isomerization of the azobenzene compound, thus a dual controlled birefringent structure, by the irradiation of light and/or by the application of the electric field, is reported for the first time.

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.
