“…In our early works the main attention was devoted photorefractive polymer composites from polyimide containing cyanine dyes J-aggregates [5][6][7][8][9][10]. After casting of polymer layers from solution, the chaotic centrosymmetrical orientation of dopants of any size is frozen in the polymers having high Tg.…”

The photoconductive, photorefractive and nonlinear optical properties of composites from polyvinylcarbazole or aromatic polyimide containing supramolecular ensembles of (tetra-15-crown-5) -phthalocyaninato gallium, indium, -phthalocyaninateacetato yttrium, -phthalocyaninato ruthenium with axially coordinated pyrazine molecules were investigated at 633, 1030 and 1064 nm using continuous and pulsed lasers. Supramolecular ensembles (SE) were prepared through dissolution of molecular metallophthalocyanines in tetrachloroethane (TCE) and subsequent treatment via three cycles of heating to 90 ∘ C and slow cooling to room temperature. The zscan method in femtosecond and nanosecond regimes was used for measuring nonlinear optical properties phthalocyaninato indium and yttrium in TCE solutions and polymer films. It was established that effect of heavy metallic atom is basic factor which determines the quantum yield, photorefractive amplification of laser object beam, dielectric susceptibility of third order and nonlinear optical properties of metallophthalocyanines.

“…[6][7][8] The method of the J-aggregate formation was earlier elaborated for similar polymer composites. 11 A solution of the polymer composite (API and Dye) in chloroform was cast onto the structure consisting of the glass slide coated with indium tin oxide (ITO) electrode and covered with the thin film (about several nanometers) thermal-evaporated Al 2 O 3 powder to prevent the hole injection from the anode.…”

“…In this report, the authors continue the study of the PR polymer composites based on nanodimension chromophores with high third-order nonlinearity. [6][7][8] Below we used the earlier proposed method of producing the polymer composites sensitive in the infrared region with a high T g (about 240 • C) based on the aromatic polyimide (API) and J-aggregates of the cyanine dyes. Figure 1 shows the structures of the API and IR-Dye sensitive to 1064 nm.…”

Photorefractive composites sensitive to 1064 nm on a base of an aromatic polyimide containing J-aggregates of a thiacarbocyanine dye are presented. The molecules of the dye form the nanocrystalline J-aggregates that are responsible for photoelectric sensitivity at 1064 nm and nonlinear third-order optical properties. The net gain coefficient 266 cm −1 and the response time 0.09 s were achieved at an external electric field of about 15 V/µm.

“…H and J aggregates of organic dyes have been known for 70 years [1,2], but they have received a huge renewed attention in the last decades because of their unique spectroscopic (e.g., extremely narrow bandwidths) and photophysical properties (e.g., superradiance) which have stimulated both fundamental studies and the search for a myriad of possible technological applications, mostly as materials for optics and optoelectronics (see [3] and, for some recent reports, [4][5][6][7][8][9]).…”

Interaction of oxacarbocyanines D-G with three polycations in aqueous solutions results in the formation of two types of likely small, distorted aggregates rather than the classical J aggregates. On the contrary, the latter are extensively and almost exclusively obtained in electrostatically self-assembled multilayers (ESAMs) prepared by alternate polycation/dye adsorption on quartz substrates. The J-aggregate growth on supported polycations is qualitatively shared by the four cyanines, a fact that reveals the crucial role of the double anionic substitutions on the dyes. On the other hand, films with D and E, which are known to have a stronger tendency to give dimers in water, exhibit higher J-band intensities and stability upon drying relative to those with F and G. Based on these observations, we suggest that energetic factors associated with cofacial dye/dye van der Waals interactions, ultimately related with the degree of planarity of the conjugated chromophores, may still play a major role in controlling aggregation equilibria in these complex systems.
