Abstract
Electroabsorption (EA) spectra of a variety of soluble nonluminescent π-conjugated polymers were measured and analyzed. We modeled the EA spectra using a summation over states model for optical non linearities with three essential states, namely 1Ag, 1B u and mA g; these are the same states which determine the EA of luminescent conjugated polymers. The model also includes relatively strong phonon interactions and a conjugation length distribution. We have not found substantial contribution to the EA spectra from either the continuum band or from the 2A g state, even though the relation E(2A g) < E(1B u) holds for our films. The EA spectrum of trans-(CH) X has been fit using a bimodal conjugation length distribution consistent with resonant Raman scattering analysis.
