โœฆ Synopsis

A new fluorescent sensor capable of sensing Cr 3+ has been synthesized. Complexing with Cr 3+ 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 Cr 3+ and it can be used as a 'naked eye' sensor. Binding of Cr 3+ was found to be reversible as the pink color disappears with excess EDTA.

## a b s t r a c t Cyanine dye Cy5 was used to be a probe for highly selective detection of trace cyanide in water by using a convenient two-phase strategy. The detection limit of both the fluorescent and colorimetric assay for cyanide is below 1.9 lM, the maximal allowance level for drinking wate
