Ratiometric fluorescence detection of cyanide based on a hybrid coumarin-hemicyanine dye: the large emission shift and the high selectivity.

Xin Lv et al.

Chemical communications (Cambridge, England), 47(48), 12843-12845 (2011-11-03)

A new ratiometric fluorescent cyanide probe was developed based on the nucleophilic attack of CN(-) toward the indolium group of a hybrid coumarin-hemicyanine dye, by which high selectivity as well as large emission shift could be achieved.
