Journal ArticleDOI
Photoinduced electron transfer from a conducting polymer to buckminsterfullerene.
TL;DR: Because the photoluminescence in the conducting polymer is quenched by interaction with C60, the data imply that charge transfer from the excited state occurs on a picosecond time scale.
Journal ArticleDOI
Photoexcitation spectroscopy of conducting-polymer-C60 composites: Photoinduced electron transfer.
TL;DR: A comparative study of the steady-state photoinduced absorption and photoinduced electron-spin-resonance spectra of conducting polymers mixed with the fullerene C 60 shows that in the case of a conjugated polymer with a degenerate ground state as donor, the structural relaxation associated with the formation of charged solitons is faster and no indications of photoinduced charge transfer are observed.
Journal ArticleDOI
Semiconducting polymers (as donors) and buckminsterfullerene (as acceptor): photoinduced electron transfer and heterojunction devices
TL;DR: In this paper, the metastable, reversible, photoinduced electron transfer between semiconducting polymers and buckminsterfullerene is reviewed. And the importance of electron-phonon coupling in these low-dimensional semiconductor polymers, resulting in structural relaxation upon photoexcitation, is proposed to contribute to the stabilization of the charge-separated state.

Journal ArticleDOI
Photoinduced absorption from triplet excitations in poly(2-methoxy, 5-(2′-ethyl-hexyloxy)-p-phenylene vinylene) oriented by gel-processing in polyethylene
L. Smilowitz,A. J. Heeger +1 more
TL;DR: In this paper, the authors used steady state photoinduced absorption to study the long-lived photoexcitations in the conjugated polymer poly(2-methoxy, 5-(2′-ethylhexyloxy)- p -phenylene vinylene) (MEH-PPV) as a dilute component in ultrahigh molecular weight polyethylene (PE) oriented by gel-processing.
