Multilayers and multichromic aggregates of anionic and cationic cyanine dyes

Abstract

The method of formation of multilayers and multichromic 3D-J-aggregates from anionic and cationic cyanines via the sequential recharge of the metal-complexis J-aggregate surface of the anionic dye, the so-called “platform,” by the cationic dye as a result of the matrix synthesis of the J-aggregate of this dye on the surface of the platform and at the subsequent J- aggregation of anionic cyanine on a positively charged surface of the 3D-platform is considered. The conclusion that a similar method offers the possibility of selfassembly of the complex systems of aggregates from the large number of dyes distinguished by both spectral properties and by the position of the electron levels in the aggregates is made.
