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]

We report on adaptive feedback control of photoinduced barrierless isomerization of 1,1'-diethyl-2,2'-cyanine in solution. We compare the effect of different fitness parameters and show that optimal control of the absolute yield of isomerization (photoisomer concentration versus excitation photons) can be
