摘要

We report the synthesis and properties of three members of a new class of photochemical model compounds containing a covalently-linked porphyrin and a cyanine dye. In compounds 1 and 2 the dye absorbs in the 450–570 nm region and energy transfer occurs with 80% 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 80% efficiency from the free ...
