Abstract
Abstract 2-Hydroxybenzyl dansyl cadaverine (DNSCH) was designed as a fluorescent chemosensor for Fe 3+ . DNSCH exhibited significant FL quenching with increasing concentrations of Fe 3+ . The presence of 15 M equiv of Fe 3+ significantly quenched the FL intensity of DNSCH. The binding constant of DNSCH towards Fe 3+ was determined and found to be 1.5 ± 0.4 × 10 −4 M −1 . DNSCH was employed as an intracellular chemosensor for Fe 3+ .
