Abstract

New fluorogenic calixazacrown (5) bearing two pyrene amide pendent groups has been synthesized. Based on ratiometric changes of monomer and excimer emissions, 5 has been found to act as a selective sensor for Pb²⁺ ion due to conformational change upon chelation of Pb²⁺ within 1:1 complex.
