Popis: It is shown that anionic indoheptamethine cyanine dyes of different structures form mixed metalcomplex J-aggregates in aqueous solutions under the action of multiply charged inorganic cations. By measuring the photoconductivity of layers from mixed metal-complex J-aggregates, it has been found that the photoresponse of nanoscale photoconverters for the IR region of the spectrum increases significantly in comparison with the indices for the J-aggregate of the individual dye. It is concluded that the formation of new highly organized structures by the self-assemblage of J-aggregates of several dyes can be considered a promising nanotechnology method for the production of organic semiconductors with improved photo properties.
