We report time-resolved photoinduced absorption and time-resolved photoconductivity in conducting polymer-C& composites. Photoinduced electron transfer occurs at times < I ps. Two subgap features are observed in the photoinduced absorption of pure poly(3-octylthiophene) (P30T); these form earlier th

Photoinduced electron transfer from the conjugated polymer poly[2-methoxy, 5-(2 -ethyl-hexyloxy)-p-phenylenevinylene] (MEH-PPV) to a SnO2 nanoporous thin ΓΏlm was studied using ultrafast IR spectroscopy. The absorption signals observed using this technique correspond to electron transfer, minimizing
