Paper Abstract

For several years, delocalized 'if-electron polymers have attracted considerable scientific interest because of electrical conductivity properties which could be associated with solitonic, polaronic, and bipolaronic species. More recently, the observation of third order susceptibilities, x(3), in the range 10-9 to 10-11 esu has generated interest in these materials for nonlinear optical applications. Electrical conductivity and nonlinear optical properties depend upon electronic characteristics such as "time-independent" and "time-dependent" electron delocalization, upon intra- and intermolecular charge transfer, and upon electron-phonon coupling. We have utilized advanced electron paramagnetic resonance techniques to characterize such electronic properties for the linear polyene polyacetylene and for a number of heteroararatic ladder polymers. The results of these measurements are used to make predictions of nonlinear optical activity.
