| Outline of Final Research Achievements |
Synthesis, characterization, and photo- and electrochemical properties of photoswitchable azo-linked porphyrin dimers that can catalyze aerobic oxidations of organic molecules were explored, and following results were obtained. 1) Primary amino-substituted free-base porphyrins, the key synthon for the preparation of the desired azo-linked porphyrin dimer, can be synthesized via palladium-catalyzed coupling of bromoporphyrins with ammonium sulfate as a nitrogen source. In addition to these studies, 2) we have developed a direct protocol for the determination of the absolute configurations of chiral mono-alcohols and epoxides using a CD-sensitive porphyrin dimer as a host molecule, which can effectively capture both oxygen atom lone pairs through simultaneous coordination with the two central metals of the porphyrin subunits.
