Article: Polyether-bridged sexithiophene as a complexation-gated molecular wire for intramolecular photoinduced electron transfer.
[show abstract] [hide abstract]
ABSTRACT: The porphyrin-sexithiophene-fullerene triad 2, where the two central thiophene units of the sexithiophene spacer are bridged with a crown-ether-like polyether chain, undergoes efficient intramolecular electron transfer from the photoexcited porphyrin moiety to the fullerene through the sexithiophene. However, complexation with a sodium cation in the crown ether ring causes complete suppression of electron transfer as a result of a drastic conformational change of the sexithiophene backbone. Furthermore, decomplexation resumes the photoinduced electron transfer. This on/off switching phenomenon indicates that the polyether-bridged sexithiophene can function as a complexation-gated molecular wire.Journal of the American Chemical Society 12/2005; 127(44):15372-3. · 9.91 Impact Factor
