title: Molecular taekwondo. 2. A new calix[4]azacrown bearing two different binding sites as a new fluorescent ionophore.
abstract: Synthesis and binding studies of a new calixarene-based fluoroionophore were made. Calix[4]azacrown having an anthracenyl unit displayed large chelation-enhanced fluorescence effects with Cs(+), Rb(+), and K(+) over other metal ion tested. Interesting "molecular taekwondo" processes between Cs(+)-Cu(2+) and Cs(+)-Ag(+) pairs were monitored via fluorescent changes.
