Fast photo-processes in triazole-based push–pull systems
Literature Information
Peter D. Zoon, Ivo H. M. van Stokkum, Albert M. Brouwer
Electron donor–acceptor compounds 1 (asymmetrical push–pull derivative) and 2 (symmetrical push–pull–push derivative) were studied in which one (push–pull) or two aniline units (push–pull–push) are connected to a biphenyl group via triazole linkers, made by “click” chemistry. Steady-state and time-resolved spectroscopies indicate that highly dipolar charge separated excited states are populated in moderately polar solvents. The very similar photophysical behavior of both compounds implies symmetry breaking in the excited state of 2. The polarity of the solvent determines the efficiency of formation of the charge separated state. While in toluene it is very low, it becomes very high in acetonitrile. The bis-triazole substituted biphenyl unit in 2 behaves as a better electron acceptor than the mono-triazole substituted biphenyl in 1, which leads to a more facile charge separation in 2. Rates of charge separation are of the order of 1011–1012 s−1, and increase with solvent polarity.

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.
