Abstract
Ultrafast nonlinear optical response in photoexcitations in polydiacetylenes (PDAs), polythiophenes (PTs), and a substituted polyacetylene (PA) were investigated.The decay kinetics in PDAs and PTs are discussed in terms of self-trapped excitons(STE), while the relaxation in the substituted PA is explained by the confinement effect of soliton-antisoliton pairs.
