Abstract
Synthesis of linear porphyrin arrays of unusual length was reported. 1,4-Phenylene-bridged porphyrin oligomers up to a nonamer (ca. 122 Å length) were synthesized by acid catalyzed condensation of formyl-substituted porphyrins with dipyrrylmethane. The absorption and fluorescence spectra of these molecules exhibit systematic changes upon the increase in the number of the porphyrins.Keywords
