SYNTHESIS OF RIGIDLY LINKED TRIAD MOLECULES BASED ON OCTAALKYLPORPHYRIN, CAPABLE OF MULTISTEP ELECTRON TRANSFER

Gribkov, A.A.,Borovkov, V.V.,Evstigneeva, R.P.,Sakata, Y.

, p. 905 - 915 (1994)

We have designed and carried out the synthesis of triad model systems containing octaalkylporphyrin, benzoquinone, and trichlorobenzoquinone with an oxidation-reduction potential gradient in the molecule.The quinone moieties are fixed relative to the porphyrin using spirononane and methylene spacers.
