title: Modulation of metal recognition by a novel calix[4]arene bearing two bipyridine units as a molecular gate.
abstract: [reaction: see text] A novel multiregulation system of ion recognition was constructed by utilizing a molecular gate. Interaction between the host and an Ag(+) is controlled with an Na(+) ion.
