Exploring the Limits of Forster Theory for Energy Transfer at a Separation of 20 A

摘要

Electronic energy transfer (EET) plays one of the key roles in natural photosynthesis, as it is primarily responsible for ensuring that the reaction-center complex is adequately supplied with photons, and has found numerous important applications in artificial analogues. Most chemical systems, including photosynthesis, transfer photonic energy between relatively closely spaced centers where Forster-type dipole-dipole theory might not be entirely valid. Indeed, there is a plethora of molecular donor-spacer-acceptor (D-Sp-A) systems where EET occurs by a through-bond mechanism.
