title: Anion-responsive covalently linked and metal-bridged oligomers.
abstract: Ethynyl-substituted acyclic anion receptors were synthesized for discrete covalently linked and metal-bridged dimers, which form various anionic complexes including double helical structures as the first examples of Cl(-)-bridged [2+2]-type complexes that are stable in the solution state.
