Synthesis of a bis(vic-diacrylic ester) porphyrin using the "3+1" methodology is described. A two-step procedure is used to convert the vic-diacrylic ester porphyrin and the bis(vic-diacrylic ester) porphyrin to the monobenzoporphyrin and the opp-dibenzoporphyrin, respectively. Characterization of the compounds by 1H NMR and UV-visible spectroscopies is also discussed.Key words: tripyrrane, diformylpyrrole, vic-diacrylic ester porphyrin, "3+1" synthesis methodology, monobenzoporphyrin, opp-dibenzoporphyrin, photosensitizer.
