Dynamics of Excitation Transfer and Charge Separation in Polymeric Semiconductors
Dynamics of optically excited electronic states have been studied in solid films and solutions of semiconducting polymers and model compounds. Transient absorption, monitored in the spectral range from 0.9 eV to 2.5 eV with a time resolution of about 100 fs, was the main experimental technique. Transient anisotropy, obtained from different polarizations of light, was employed to trace the dipole m
