Paper Abstract

Polymerization of acetylene on metallocomplex catalysts was studied. It was shown that morphology, stability and optical properties of polyacetylene (PA) compositions depend on the conditions of the PA solid phase formation. Using catalysts base don Re in highly viscous polyvinylbutiral solutions allows to obtain high stable compositions of trans- nanopolyacetylene (NPA) with unique optical properties. Compositions of NPA could be prepared in the form of solutions, films and plates. They are characterized by: (1) Vibrational structure of cis- and trans- bands in optical absorption spectra; (2) Absence of the low-energy peak in photoinduced optical absorption spectra; (3) Extremely low intensity of fluorescence; (4) Passband in the near-IR region; (5) High intensity of Stokes and anti-Stokes lines of the fundamentals of polyene chain in resonance and off- resonance Raman spectra. Compositions of NPA could be used as material for: (1) Different types of switches and sensors: (2) Raman lasers; (3) Micro label for security of objects and documents against forgery. Raman scattering recording instruments for NPA compositions could be designed based on standard digital camera, laser pointer, longpass filter and two or three lenses.
