Free standing polyacetylene film (FS-PA) is one of the most promising materials for research purposes and for applications in optoelectronics. First time FS-PA was synthesized by Prof. H.Shirakawa and his coworkers in 1971. These films show record values of non-linear third-order optical susceptibility and their conductivity after doping is equal to that of copper. In 2000 ALAN J. HEEGER, ALAN G. MacDIARMID, and HIDEKI SHIRAKAWA won Nobel Prize in chemistry for this discovery. The low stability of FS-PA is the major obstacle on the way of practical applications of this material.


In 1989 Dr. V.M. Kobryanskii has developed a new modification of PA. It was shown that the polymerization of acetylene on a catalytic system composed of binuclear rhenium complexes and reducing agent, in solution of saturated polymers leads to soluble compositions containing nanoparticles of PA with very low concentration of conformational and chemical defects. This material was referred to as nanopolyacetylene (NPA). In contrast to the known PA modifications, NPA is extremely stable, could be prepared in the form solution, film and plate, and exhibit a number of unique optical, physical and chemical properties. It characterized by anti-Peierls transition at lowering temperature and can be used for development of high-temperature organic superconductors.

Nano-composites of conjugated monomers, conjugated polymers and carbon nanotubes.

In 1997 - 2003 Supermat Intl. has developed the method of preparation of 3D ordered nano-gels and nano-composites of conjugated polymers and carbon nanotubes. These materials possess long lived coherent vibrations along the chains and between nanoparticles at laser excitation. They demonstrate unique opto-electronic properties and can be colled coherently ordered materials.
