ABSTRACTWe discuss two important aspects of the nonlinear optical response of polyacetylene, the prototype conjugated polymer. In the subband gap region, χ(3) of polyacetylene has a rich spectral response and its magnitude is found to be the largest among semiconductors. In the superband gap region, absorption of photons leads to direct photogeneration of charged solitons on a femtosecond-time-scale. These results are discussed in the context of a one-dimensional, coupled electronlattice system, and are generalized to other conjugated polymers.

Conducting polymers comprises a new class of materials achieving electrical conductivities which rival those of the best metals. The parent compounds (conjugated polymers) are quasi-one-dimensional semiconductors. These polymers can be doped by electron acceptors or electron donors. The prototype of these materials is polyacetylene (PA). There are various other conjugated polymers such as polyparaphenylene, polyphenylenevinylene, polypoyrrole or polythiophene. The doped systems, i.e. the conducting polymers, have intersting potential technological applications such as replacement of conventional metals in electronic shielding and antistatic equipment, rechargable batteries, and flexible light emitting diodes.Although these systems have been investigated almost 20 years, the electronic structure of the doped metallic systems is not clear and even the reason for the gap in undoped semiconducting systems is under discussion.
