1,4-Phenylene-bridged Subporphyrin-Porphyrin Dyad, Triad, and Tetrad
1,4-Phenylene-bridged subporphyrin-porphyrin hybrid molecules were prepared by the Suzuki-Miyaura cross coupling reaction of meso-(4-bromophenyl)-substituted subporphyrin 2 and 5-pinacolateboryl porphyrin 3. In all hybrid models examined, intramolecular energy transfer from the subporphyrin moiety to the porphyrin moieties proceeds efficiently.
