Halogenbrücken und eine optische Sonde …︁ …︁ als Merkmale einer verzahnten Wirtstruktur ergeben ein wirksames Anionensensorsystem. Wie P. D. Beer et al. in der Zuschrift auf S. 11642 ff. zeigen, dient ein ausschließlich halogenverbrückender Rotaxan‐Wirt mit photoaktivem Rhenium(I)‐Bipyridyl‐Zentrum in der makrocyclischen Komponente als optischer Lumineszenzsensor für Halogenidionen mit hoher Bindungsaffinität...
The synthesis and anion binding properties of the first rotaxane host system to bind and sense anions purely through halogen bonding, is described. Through a combination of polarized iodotriazole and iodotriazolium halogen bond donors, a three‐dimensional cavity is created for anion binding. This rotaxane incorporates a luminescent rhenium(I) bipyridyl metal sensor motif within the macrocycle component,...
