Abstract:

A change in optical properties of conducting polydiacetvlene THD poly-1,1,6,6- tetraphenylhexadiinediamine under doping has been investigated for the first time. Spectral dependencies of extinction coefficient were studied in the range 400-25000cm either for non-doped PDA THD or for doped polymer at various doping levels. The obtained data allow to suggest that in PDA with conductivity 10exp14cm a high concentration of the charge carriers takes place. The observed sufficiently low macroscopic conductivity is attributed to the complicated hierarchy of structural units which is typical of polymeric materials. The results are compared to the corresponding data obtained for conducting polyacetylene.
