Multilayer J-aggregates of cyanine dyes

Abstract

It is shown that the introduction into the aqueous solution of anionic thiamonomethinecyanine of the Mg²⁺ cation promotes the formation of the multilayer dye J-aggregates. It is also established that, on the J-aggregates or on the metallocomplex J-aggregates of anionic thiamonomethinecyanine, a multilayer and simultaneously multichrome system of new J-aggregate is formed due to the additional introduction of cationic cyanine dye into the solution, which absorbs light in a different region of the spectrum than anionic dye.
