A novel chemosensor was designed and synthesized for various analytes: Fe 3+ , Fe 2+ , Al 3+ and pyrophosphate. The sensor showed a selective color change from yellow to orange toward both Fe 3+ and Fe 2+ in a near-perfect aqueous solution, which cou

A new fluorescent sensor 1 was prepared by bridging a 7-nitrobenzo-2-oxo-1,3-diazolyl (NBD) fluorophore with a dimethyl ethylene amine group via an ethylamine spacer. Distinct “turn-on” fluorescence changes of 1 were observed upon the addition of
