Project summary

The Project is aimed at the extensive study of polymeric composites and polymers containing supramolecular aggregates suitable for use in opto- and microelectronics. Charge carrier transport, electroluminescent characteristics, nonlinear optical properties and injection in these materials will be studied and search for promising applications will be carried out.

The most important results, obtained in the framework of the ISTC Projects 872 and 2207, which form a solid basis for further development in this area, are as follows:

  1. J-aggregates formed by cyanine dyes in the polyimide matrix were found to produce a narrow band efficient electrolumenescence, thus providing an excellent opportunity for their use in light emitting diodes.
  2. Interphase doping of properly prepared polyaniline films deposited on the surface of particular metals leads to the record conductivity. This makes such materials very promising for manufacture of components of various electronic devices.
  3. New photorefractive composites based on materials having high third-order optical nonlinearity have been developed. These materials have photorefractive characteristic comparable to the best ones of traditional polymer materials. At the same time, they have high glass temperature and, thus, are much more stable than traditional photorefracive materials.
  4. Energetic disorder at the interface between organic materials and metals was found to have very peculiar properties that affect injection of charge carriers into organics.
  5. New method for easy detection of the influenza virus using polyaniline complexes has been developed.

These results will be used as a starting point for materials development for electroluminescent and electrochromic displays, photorefractive devices, and solar cells.

J-aggregates of cyanine dyes and other organic molecules will be studied for possible use in light emitting devices. Flexibility of the aggregates’ structure enables the creation of a new set of devices, the properties of which can be tailored at the quantum mechanical level.

Photorefractive polymers attract a good deal of attention nowadays in respect of their possible application in optoelectronics. Significant attention will be paid to the development of new photorefractive (PR) polymer composites based on carbon nanotubes and supramolecular structures sensitive to laser action in broad spectral range from visible to near IR region (up to 1600 nm). Such materials seem to be very promising for use in a PR-based method for medical diagnostics of living organisms and for telecommunication applications.

Properties of new interpolymer complexes between polyaniline and various polyacids will be studied. It has been recently discovered that under proper treatment such complexes demonstrate exceptionally high conductivity and have other useful properties (such as chirality and electrochromism). New highly selective and easy to use sensors and absorbents for the influenza virus, based on the complexes between polyaniline and polyacids, will be developed.

Significant attention will be paid to the development of organic and hetero-organic hybrid supramolecular materials suitable for manufacture of stable organic solar cells with conversion efficiency over 4%.

An integral part of the Project is a theoretical study of charge carrier injection and transport in organic devices. Various analytical and computer simulation methods, developed in the framework of Projects 872 and 2207, will be used to resolve this problem. In the proposed Project the main attention will be focused on the study of the effect of local order on transport properties of organic materials as well as on transport in case of high concentration of charge carriers.

We believe that successful realization of the proposed Project will lead both to the increase of a fundamental knowledge of the properties of conducting polymers and nanocomposites and to promising applications of these materials.
