General description

1,1′-Diethyl-2,2′-cyanine iodide is a quinocyanine dye. This photographic sensitizing dye is mainly used in silver halide photography. 1,1′-Diethyl-2,2′-cyanine iodide dye aggregation in dilute aqueous solution displays red and blue shifted absorption bands.[1]

Application

1,1′-Diethyl-2,2′-cyanine iodide has been used as an absorber in a method to correct the fluorescence excitation-emission matrix (EEM).[2]
