derivatives. As a consequence, excited states are blueshifted and the nonlinear susceptibility is reduced. Ab-
sorption by aggregates, which can be obscured by scattering and interference, is clearly revealed by electro-
absorption spectroscopy. The reduced symmetry of 1,3-PPV modifies optical selection rules, resulting in strong
overlap of the fluorescence spectrum with excited state absorption by charged polarons. | en |
