Physical properties (optical, electron, electrooptical etc.) of such nanosystems essential determinates by organic molecules type, form and material of nanoparticles and interface properties of the nanoparticles-adsorbed molecules. Creation of the assign in advance properties nanosystem draws out such fundamental and applied tasks: development of the nanocomposits receiving method, investigation of its structure and physical properties on the atomic and molecular level. In the present work: 1) have been received on atomically smooth surfaces of gold and graphite the self arranged layers of the long-chain of aliphatic, polyconjugate aromatic molecules and fullerenes; 2) have been developed the technology of the production of light emitting planar nanocomposits based on the gold particles and the organic phosphor Alq3; 3) have been developed and produced the three-terminal circuit for investigation of the influence of transverse electric field on the conductivity and electroluminescenceсe of the nanocomposits; 4) have been studied the influence of the anthracene thin film on the improvement of electroluminescent properties of a planar light emitting nanocomposits; 5) have been developed a method of preparing of the nano-chains light emitting structures by the nanolithography with the using of polystyrene microspheres; 6) theoretically have been investigated the spectral properties of molecules of matters with the prognoststic transfer of electron excitations, by the example of the molecules of oxyfenilnaftalimyd by spectral methods has been confirmed the neutral excitation transfer from the aminofenil group to the naftalymid one; 7) at the frame of analytical approach has been carried out the calculation of the optoacustical effect of sound generation by metal nanoparticles immersed to the dielectric matrix; 8) theoretically have been discovered the dependence of generated sound intensity of the nanoparticles form and property; 9) has been created the theory of the optoacustical influence of the laser irradiation on the dielectric matter with incorporated nanoparticles, has been proposed and realized the construction of diode planar light emitting cell based on the Au nanoparticles and anthracen layers; 10) on the base of Au particles and tetracen layers has been developed the construction of light emitting transistor with the low "source-drain" voltage and has been shown that the light modulation of the proposed transistor may be carried out by the control electrode; 11) has been developed, manufactured, and certified the light emitting diode with the stable parameters and a high density of the luminescence centers; 12) has been received the effective electroluminescence at the low voltage from the nanoconductive tetracene/gold structures preparing by nanosphere lithography; 13) theoretically predicted and experimentally confirmated the directional character of a triplet electron excitations in the dodecanucleotid complexes, have been presumed that I versus V characteristics of the molecular complexes should have the diode characteristics; 14) has been ascertained the role of the inelastic electron-transport processes on the current formation in the separate molecule that located between of two metal electrodes (the one molecule diode); 15) have been manufactured and investigated at molecular level a high ordered monolayer films of the silan and alcanthyol derivated on Au(111) surface; 16) for the first time have been manufactured high ordered porous monolayer films of the thiophen and thriathanaftalen derivated. On the base of the research effort have been deductioned the summary concerning on atom and molecule interaction in the thin films, influence of the organic phosphor Alq3, thin films of the tetracen, the molecule ordering of monolayer films of the silan and alcanthyol thiofens derivated on the surface Au(111) and manufactured high-ordered porous monolayer films of tyophen and thriasanaftilen derivated. The deductioned scientific summary give us possibility to form practical recommendation on development of the scientific and technology fundamentals of the such directions as improvement of electroluminescent properties of planar light emitting nanocomposites, production new light emitting structures with enhanced efficient of glow and low working voltage that is long-range for a creation of the efficient nanosized sources of light; the investigations would be used at the development the elements of new microelectronics generation (nanoelectronics), and also enables a new possibilities for control on adsorption properties of a surface and the purposeful influence on surface processes, and use the recommendation for development of the technologies of molecular electronics, creation of a new electron and light sources, control of surface structure and properties, receiving of the different assignment organic films.
