Time dependent density functional theory (TDDFT) and transition state theory (TST) have been performed to study the dehydrogenation process of dihydrogen bonded phenol–borane-trimethylamine (phenol–BTMA) in the excited state. The potential curve of phenol–BTMA in the ground state confirms that the dehydrogenation process does not occur in the ground state. The analysis of the geometric structure and infrared spectra demonstrate that the dihydrogen bond O–H⋯H1–B of phenol–BTMA is considerably strengthened with the cleavage of O–H when excited to the first excited state. Based on the geometric structure in the first excited state, a transition state is found with the only imaginary frequency pointing to the formation of the hydrogen molecule. This finding implies the occurrence of the dehydrogenation process of phenol–BTMA in the excited state. The dehydrogenation reaction is fully completed in the reaction product and the new formed hydrogen molecule moves away from the plane of the benzene ring. This work provides a theoretical model for the dehydrogenation process of phenol–BTMA in the excited state.

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.
