“…It is connected with the fact that the dipole moment and the way of the transfer of charge carriers from intramolecular electron donor is not on the intramolecular acceptor fragment but to the intermolecular acceptor with high electron affinity. Moreover, intermolecular acceptor delocalizes of not one, but a larger number of carriers [8]- [12]. Qualitative picture is shown in Fig.2, left part.…”

Abstract. In the current paper, a unique role of the photorefractive features of the nano-and bio -doped organic systems has been considered as an indicator of the change of dynamic, structural, spectral and conductive characteristics. The paper presents some innovative views about the tendency towards the concurrent role of the bioobject sensitization of the organic matrixes in comparison with the nano-object doping one. The results have been supported both by the experimental four-wave mixing technique data as well as by the qualitative model.

“…This approach has been extended for the estimation of the refractive parameters of the nanoand bio-structured organics in the papers [8]- [12]. Using Raman-Nath diffraction conditions the laserinduced change of the refractive index can be estimated as following:…”

“…The experiments have been made at a nanosecond pulsed regime at the spatial frequency of 90-130 mm −1 and at the laser energy density ranged from 0.01 to 0.6 J⋅cm −2 . The technical experimental scheme has been analogous to that it can be explained in detail (Kamanina & Vasilenko, 1997, Kamanina & Vasilenko 1995 and was recently shown in (Kamanina et al, 2015) in the modified variant.…”

Because of the unique energetic, refractive and photoconductive characteristics of effective nano-objects, especially carbon nanotubes, the modification of optical properties of the organic and inorganic materials can be considered as the preferable one via the use of the nanostructuration process. Emphasis has been given to the incorporation of nanoobjects directly in the materials' body and on their surface. Under the conditions of a surface treatment of the inorganic structures, an IR-laser at the wavelength of 10.6 micrometers was used to orientate carbon nanotubes deposited in the electric field of 100-600 V×cm -1 . Dramatic spectral and mechanical parameters changes have been found. Refractive features of the nanostructured organics have been studied via applying the second harmonic of the pulsed Nd-laser at different spatial frequencies and under the nanoparticles sensitization doping such as fullerenes, carbon nanotubes, shungites, quantum dots, and graphenes. A drastically obtained laser-induced refractive index has been established. A prediction has been proposed to extend the area of the application of the systems considered.UDC Classification: 535; 538.9; 539; 544; DOI: http://dx

“…Moreover, the tendency of the change of the nano-doping to bio-doping one has been discussed because the bio-doped organics have shown the same refractive parameters change [37,38]. The correlations indicated above can be used, on the one hand, for the basis of the predicted paths to extend the use of organic conjugated structured materials for the industrial and the biomedical applications, on the other hand, for the assessing of the ability of the competing influence of bio-objects, in comparison with nano-objects, due to nontoxicity and easy renewability from the World Ocean these biological structures.…”

In the current chapter, the results of the optimized organic and inorganic materials features have been presented and discussed under the conditions when the material volumetric body and their surfaces have been structured. The dramatic change of the main characteristics of the inorganic matrix which surface has been modified with oriented carbon nanotubes and additionally treated by surface electromagnetic waves has been established. The transmittance and reflection spectral change, of the micro-hardness and of the wetting angle increase have been discussed due to the covalent bonding of the carbon nanotubes with the near-surface materials layers. Analytic and molecular dynamics simulations have supported the data. The essential change of the basic macro-parameters of the organic matrix, including the liquid crystal one, via their structuration with the nano-and/or bio-objects such as the fullerenes, carbon nanotubes, shungites, quantum dots, graphene oxides, DNA has been found. The spectral, photorefractive, and photoconductive characteristics modification has been discussed due to the drastic increase of the dipole moment. The laser-induced change of the refractive index has been considered as the indicator of the basic materials macro-parameters changing. It has been predicted that a scientific knowledge and the technology advances can be useful for the solar energy, display technique, for the system to absorb the gas and impurities, for the schemes with the compacted information recording as well as for the biomedicine.
