Abstract

2-Hydroxybenzyl dansyl cadaverine (DNSCH) was designed as a fluorescent chemosensor for Fe³⁺. DNSCH exhibited significant FL quenching with increasing concentrations of Fe³⁺. The presence of 15 M equiv of Fe³⁺ significantly quenched the FL intensity of DNSCH. The binding constant of DNSCH towards Fe³⁺ was determined and found to be 1.5 ± 0.4 × 10^-4 M^-1. DNSCH was employed as an intracellular chemosensor for Fe³⁺.
