Mimicry of electron transfer in the photosynthetic Reaction Centre{-specifically the primary electron transfer step be- tween the special pair of bacteriochlorophyls and the bacterio- pheophytin-is generally approached using multiporphyrins. Modulation of the electronic properties of the intervening medium between the donor and acceptor chromophores is of particular interest, and has been addressed by varying covalent2 as well as non-covalent3 bonds. An approach by which ...
