Nanopolyacetylene: optical properties and practical application

New highly-ordered compositions of nanopolyacetylene (NPA) were recently synthesized. These compositions are highly stable and could be prepared in the form of solutions, films or fibers. Raman scattering in NPA exhibits high intensity of Stokes and anti-Stokes lines; long sequence of overtones and combination bands; extremely low intensity of fluorescence, and passband in the near-IR region. These properties of trans-NPA compositions suggest many important practical applications of this polymer as key photonic material for development of new types of Raman shifters.
