This feature article presents cyclophane-based host–guest complexes for which electronic interactions between the host and guest molecules can modulate excited-state properties in an advanced way involving both singlet and triplet excited states.
This report highlights recent reports of bacteria-derived cyclophane-containing peptides from radical SAM/SPASM enzymes. The strategies for discovery, structures of the products, bioactivity, mechanism of formation, and synthesis are discussed.
Cyclophanes incorporating o-xylylene or mesitylene-m-cyclophane linked-selone groups are mutually syn in both solid state and solution. While, m-xylylene or p-xylylene cyclophanes linked-selone groups show syn and anti conformations in the solution.
Here we investigate how structural changes stabilise (or destabilise) indolcarbazole-based diradical systems, demonstrating that they are very useful motifs for dynamic covalent chemistry.
Switchable cyclophanes allow capture/release of guests to control their properties.
