要旨

The first experiments on trapped rotaxanes are presented, combining collision induced fragmentation and in-trap laser spectroscopy. The intrinsic optical properties of three rotaxanes and their non-interlocked building blocks (thread and macrocycle) isolated in a quadrupolar ion trap are investigated. The excitation and relaxation processes under thermal activation as well as under photo-activation are addressed. The light and collision induced fragmentation pathways show that the degradation mechanisms occurring in the rotaxane are highly dependent on the nature of the thread. In the prospective of operating photoswitchable molecules, photo-activation is achieved in a controlled way by depositing photo-energy in the desired sub-unit of a mechanically interlocked structure.

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.
