Theoretical study of the mechanism of the solvent dependency of ESIPT in HBT
Literature Information
Keiji Naka
2-(2′-Hydroxyphenyl)-benzothiazole (HBT) has been widely studied for use as a system for excited-state intramolecular proton transfer. However, the mechanism underlying the solvent dependency of HBT fluorescence spectra remains unclear. In this study, the HBT photochemical process in the S1 state was analysed using density functional theory (DFT) and time-dependent density functional theory (TDDFT). The excited-state intramolecular proton transfer in the enol form of HBT was found to depend on the hydrogen-bond acceptability of the solvent. The twisting of the keto form of HBT is determined by whether HBT acts as a hydrogen-bond acceptor or donor. A specific stacking structure of the enol form of HBT was found to decrease the S1 → S0 transition energy, which corresponds to the experimental fluorescence spectra in a DMSO/H2O solution mixture.

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.
