- Abstract
- Energy transfer in a series of hetero-dyads of zinc porphyrin and free-base porphyrin connected
at the b position by p conjugated bridges has been determined. The dyads have been
characterized and compared with the homo dyads, excellent models for the donor and the
acceptor porphyrins in the electronically conjugated system. The homo dyads provide reliable
parameters for the determination of the energy transfer rate calculated according to the Fo¨ rster
theory. This model was inadequate to account for the experimental findings and an electron
exchange mechanism was shown to contribute. A favorable coplanar arrangement of the bridge
and the tetrapyrroles facilitates the energy transfer process, which displays a very low distance
dependence and an efficiency >98%. (literal)
