title: Chloride coordination by oligoureas: from mononuclear crescents to dinuclear foldamers.
abstract: A series of acyclic oligourea receptors which closely resemble the scaffolds and coordination behavior of oligopyridines have been synthesized. Assembly of the receptors with chloride ions afforded mononuclear anion complexes or dinuclear foldamers depending on the number of the urea groups.
