A new anthracene derivative of calix[4]arene as a uorescent chemosensor

Abstract

A new anthracene derivative of calix[4]arene was synthesized as a highly fluorescent compound. This compound was examined for its fluorescent properties towards different metal ions (Li+ , Na+ , Mg2+ , Ca2+ , Ba2+ , Ni2+ , Cu2+ , Zn2+ , Pb2+) by UV and fluorescence spectroscopy. On complexation by alkaline earth metal cations and transition metal cations, the fluorescence spectrum was quenched. In particular, Ca2+ caused greater than 98% quenching of the anthracene derivative of calix[4]arene.© TÜBITAK.
