Recent Surprises in the Study of Photoinduced Electron Transfer: Covalent Versus Non-Covalent Pathways

  • Chapter

Part of the book series: NATO ASI Series ((ASIC,volume 512))

Abstract

Stepwise photoinduced charge separation in a rigid trichromophoric system with a U-shaped conformation is described. In the thus produced totally charge-separated state the plus and minus charges reside on the termini of the U-shaped molecule with a separation of about 16 Å measured ‘through-space’ against about 27 Å as measured via the shortest ‘through-bond’ pathway. Charge recombination to the ground-state is found to be accompanied by charge transfer fluorescence. Both from the overall rate of this recombination and from the radiative rate constant of the accompanying charge transfer fluorescence it appears that the interaction between the termini is much stronger than can be accounted for by a pure through-bond mechanism.
