Abstract
- A rationally designed Schiff base chemosensor (L) could render specific detection of Al 3+ ions with two distinct turn-on emission signals, separated by over 100 nm upon excitation at two different wavelengths. The utility of the probe lies in facilitating sensing in 80% aqueous medium with an emission close to 600 nm via an intramolecular charge transfer (ICT) mechanism. The biocompatible and cell permeable probe could readily sense Al 3+ in live HeLa cells as well. The affinity of the probe for Al 3+ could be leveraged to specifically study DNA- Al 3+ interaction in solution. [ABSTRACT FROM AUTHOR]
