Abstract
The photophysics of conducting polymers from the poly(para-phenylene vinylene) (PPV) family are studied using femtosecond transient absorption to address several issues namely: the primary photoexcitation; interaction under high excitations; and biexciton signatures. The solutions and films of the PPV oligomers MEH-DSB and several soluble PPV derivatives are measured with similar results. The femtosecond differential transmission (DT) spectra in MEH-DSB show a positive band due to stimulated emission around 2.4 eV and a photoinduced absorption band from 1.3 to 2.0 eV.
