The focus of the research was to obtain high performance properties electrical andor optical from conjugated polymers by improving the structural order through polymer processing. The success of the approach is quantified by the demonstration of third order optical susceptibility values in excess of 10 to the minus 8th power, 10 to the minus 7th power esu for high quality, oriented trans-polyacetylene at frequencies in the infrared frequencies which are relevant to optical communications. Equally important, we have identified a structureproperty relationship that can be used to direct synthesis of new conjugated polymers with comparably large NLO coefficients In conjugated polymers with degenerate ground state, the dominant NLO mechanism results from the neutral soliton Ag intermediate state mechanism. In a parallel effort, high performance electrical and mechanical properties were demonstrated in fibers made from conducting polymers.
