A new fluorescent sensor capable of sensing Cr3+ has been synthesized. Complexing with Cr3+ triggers the formation of a highly fluorescent ring-open form which is pink in color. The sensor shows extremely high fluorescence enhancement upon complexation with Cr3+ and it can be used as a “naked eye” sensor. Binding of Cr3+ was found to be reversible as the pink color disappears with excess EDTA. © 2009 Elsevier Ltd. All rights reserved
