A series of oligo-<I>para</I>-phenylene (OPP) substituted new porphyrins was prepared by the combinations of aryl coupling reactions and Lindsey's pyrrole condensation reactions. Low field shifts of OPP protons in <SUP>1</SUP>H-NMR spectra became larger when the protons locate closer to the center of the molecule.
