Abstract

The development of a fluorogenic chemosensors with high sensitivity for copper ion (Cu2+) has been receiving great attention in recent years because of their potential application in clinical biochemistry and the environment studies. In the present study, we designed and synthesized a fluorescent probe, Np‐azaCE, with 1,8‐naphthalimides as a core structure and 1,4‐diaza‐9‐crown‐3‐ether as a copper ion tweeze, which showed selective and sensitive fluorometric change upon addition of a copper ion. The Np‐azaCE chemosensor was highly selective for Cu2+ over the other metal ions with fluorescent quenching. Finally, the Cu2+ detection limit and job's plot of Np‐azaCE were calculated using UV–visible spectrophotometer and fluorescence spectrophotometer. [ABSTRACT FROM AUTHOR]

The Np‐azaCEchemosensor was highly selective for Cu2+over the other metal ions with fluorescent quenching. Finally, the Cu2+detection limit and job's plot of Np‐azaCEwere calculated using UV–visible spectrophotometer and fluorescence spectrophotometer. This article describes the preparation and analysis of Cu2+‐sensing naphthalimide‐based chemosensors (Np‐azaCE).
