Machinelike behavior—reversible dethreading and rethreading of a molecular bead—is demonstrated in a self‐assembled monolayer (SAM) of a pseudorotaxane on gold. Furthermore, unprecedented ion‐gating behavior associated with threading and dethreading is observed; the SAM blocks or allows the access of electroactive species to the electrode surface depending on the presence or absence of the threaded molecular bead (see picture).
Reversibles Ab‐ und Wiederauffädeln von Cucurbiturilmolekülen wird bei einer selbstorganisierten Monoschicht eines Pseudorotaxans auf Gold beobachtet. Je nach An‐ oder Abwesenheit eines Cucurbituril‐„Rades“ auf der „Achse“ blockiert oder ermöglicht die Monoschicht den Zugang elektroaktiver Spezies zur Elektrodenoberfläche (siehe Bild).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
