A new fluorescent nano-chemosensor (L) has been synthesized and characterized by 1H NMR, 13C NMR, diegojavierfares.com COSY, HSQC, DEPT, IR spectroscopy, elemental analyses and scanning electron microscopy.The fluorescent nano-chemosensors with size about 30 nm were prepared by nanoprecipitation method.The chemosensor L showed selectivity to Al3+ and Cr3+ cations in tillman 750m EtOH/H2O (1:1, v/v) mixture.

This chemosensor also exhibited an improved sensitivity and selectivity to Al3+ and Cr3+ cations when used as insoluble nanoparticles in aqueous buffer solution.
