A New Methal Sensory System Based on Intramolecular Fluorescence Quenching on the Ionophoric Calixarene Ring

Aoki, Izuo,Sakaki, Toru,Shinkai, Seiji

, p. 730 - 732 (2007/10/02)

To design a new metal sensory system, calixarene bearing pyrene (as a fluorophore) and nitrobenzene (as a quencher) near the ionophoric cavity is synthesized: in response to the metal-binding event the fluoroscence intensity is dramatically enhanced.
