Abstract

A new calix[4]arene-based fluorescence chemosensor displaying a strong excimer emission was prepared. When a Pb²⁺ ion is bound to the two amide oxygen atoms linked to the fluorophores, the ligand exhibits a marked quenched excimer emission due to its geometrical change during the complexation. By the addition of Ca²⁺ ion into the 1·Pb²⁺, the excimer emission band was revived, by which an interesting on/off switch process is proposed.
