Abstract
Macrocyclic ethers are used extensively for their ability to form strong and selective interactions with charged species. It has been shown that the incorporation of heterocyclic groups into macrocylclic ethers increase rigidity and interaction with certain ions. Alkylation of these azacrowns with benzylic halides can attach fluorionophoric substituents onto the ring. One of the molecules used for this alkylation is 5-chloro-8-methoxy-2-(bromomethyl)quinoline. Azacrowns with this alkyl ligand have displayed interesting ion complexation properties.
