Abstract

A naphthalimide based fluorescent probe ‘1’ that operates based on photoinduced electron transfer phenomenon is synthesized and its chemosensory application is explored. Among various metal ions, 1 selectively detects Fe³⁺ with a detection limit of 3.0 × 10⁻⁸ M. 1 is stable at physiological pH, nontoxic under experimental conditions and suitable for the detection of Fe³⁺ ions present in aqueous samples and live cells.
