A sleeping host awoken by its guest: Recognition and sensing of imidazole-containing molecules based on double Cu2+ translocation inside a polyaza macrocycle

pH-driven double Cu2+ ion translocation occurs inside an heteroditopic macrocycle. The movement opens and closes the system allowing or preventing it to function as receptor for bidentate anions. When imidazole is added to a solution buffered at an appropriate pH value, opening of the system and substrate binding can be induced by the substrate itself, which results in a sharp color change (see picture).
