Abstract

Excited state intramolecular proton transfer (ESIPT) in 1-chloroacetylaminoanthraquinone (CAAQ) and 1,8-dihydroxyanthraquinone (DHAQ) in solution is investigated at room temperature by means of femtosecond transient absorption spectroscopy. While ESIPT is practically instantaneous in DHAQ, in CAAQ the same process occurs with measurable kinetics, with a time constant of 100 fs. The energy diagrams for the ground and excited states of the proton-transferred and non-proton-transferred species, compatible with these observations, are discussed and an estimate is given for the activation energy of the process.

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.
