摘要

A stilbenophane and protonated azobenzenophanes (“pseudo-stilbenes”) with four –CH2–S–CH2– bridges in all meta-positions were synthesized. The spectroscopic and photochemical properties were investigated: excited dimer absorption spectra and for the stilbenophane also emission spectra were observed. Photochemical reactions could be identified as the [2+2] photocycloaddition for the stilbenophane; the nature of the photoproducts in the case of pseudo-stilbenes could not be established. Photo-isomerizations could not be observed which gives a negative answer to the title question.

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.
