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+-Cu2+ and Cs+-Ag+ pairs were monitored via fluorescent changes.
