Photochemical reduction of xanthone in an alcoholic solution flowing in a column packed with MCM-41, a mesoporous silica, was dependent on the magnetic field. The free radical intermediates were detected by the spin trapping method and the yield of spin adducts was also dependent on the magnetic field. In addition, a radical-quenching experiment was made to analyze the bulk concentrations of the free radical intermediates as functions of the magnetic field. Although these magnetic field dependencies were different from those observed in the micelle, we concluded that these observations are explained with the “relaxation mechanism” of the radical pair model: i.e. the intermediate radical pair in a cage has a life span comparable to or longer than the spin lattice relaxation times of these radical intermediates. The mechanism and characteristics of this cage effect in the nanotube, which is opened at the both ends, are discussed.

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.
