We report the synthesis and properties if three members of a new class of photochemical model compounds containing a covalently-linked porphyrin and a cyanide dye.In compounds 1 and 2 the dye absorbs in the 450-570 nm region and energy transfer occurs with 80percent efficiency from the dye to the free base porphyrin.In compound 3 the dye absorbs in the 650-780 nm region and energy transfer occurs with 80percent efficiency from the free base porphyrin to the dye.The zinc-porphyrin-dyes exhibit both donor and acceptor quenching with only moderate yields of energy transfer.This work is a first step toward the development of an artificial phycobilisome.
