A new fluorescent nano-chemosensor (L) has been synthesized and characterized by 1H NMR, 13C NMR, 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 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.
