title: One-Pot Synthesis of Strained Macrocyclic Pyridone Hexamers and Their High Selectivity toward Cu(2+) Recognition.
abstract: The removal of Cu(2+) ions is relevant to environmental pollution control and neurodegenerative disease treatment. A novel family of strained macrocyclic pyridone hexamers, which exhibit highly selective recognition of Cu(2+) ions and reduce copper content in artificial seawater by 97% at a very low [host]:[CuCl2] molar ratio of 2:1, is documented.
