Özet

We have constructed a novel fluorescein-based fluorescent chemosensor, FL-In, functionalised with an indole moiety and capable of sensing by both the optical "turn-on" and electrochemical detection of carbonate ions (CO32-) in aqueous media. The probe exhibits excellent selectivity and a low detection limit (0.27 mu M) regarding carbonate ions by a possible coordination and hydrolysis reaction mechanism. The developed probe successfully detected CO32- ions in different samples of water. Also, in a simple filter paper experiment, we documented its ability to allow the monitoring of CO32- with the naked eye. Grpahical Abstract
