Nanometer films of polymethine dyes in optical memory and nonlinear optics

Influence of molecule-substrate interaction on component composition of cyanine thin films

“…Studies to improve performance of devices on the basis of molecular layerslight-emitting diodes, field transistors, and dichroic color filters for LC displays are underway [12]. Lasing on J aggregates in thin cyanine dye layers has been demonstrated [10].…”

“…Also, they are used as photosensitive elements of Gratzel solar cells [7][8]. Cyanine dyes and their J aggregates have large third-order susceptibility, i.e., are nonlinear materials [9][10]. These aggregates are used in optoelectronic as subpicosecong photochemical switchers [11].…”

The mechanisms of the photostimulated structural changes in molecular layers of cyanine compounds

“…Thin films and molecular layers of organic compounds are used in a variety of scientific and technical areas, from the study of cell membranes 1,2 , to the development of nonlinear optical elements 3 , and solar cells 4 , OLED, and field-effect transistors 5 . The above structures allow preparation of smart chemical bond distribution in organic molecules, which will affect the distribution of electron density in various molecular entities, the transfer of excitation energy of light-excited molecules, and their ability to stereoisomerization, a basis of almost any optoelectronic system 6 .…”

Formation mechanisms of the component composition for thin films and aqueous solutions of symmetric cyanine dyes

“…The films of such dyes are used as media for recording information by optical methods [2,3], as the photosensitive layer in dye-sensitized solar cells [4], photosynthetic systems [5], in medicine as components of microcapsules, microprobes, etc. [6].…”
