Outline of Final Research Achievements

We synthesized phosphole-fused porphyrin dimer for the first time as a representative of a new class of porphyrins with a phosphorus atom. This porphyrin dimer possesses excellent electron-accepting character. Then, we synthesized octaphyrins with a dithieno[3,4-b:3',4'-d]thiophene unit as thiophene-fused dithiaoctaphyrin. The octaphyrins revealed cross-conjugated and macrocyclic 36π-electron networks.
In addition, we synthesized dithieno[3,4-b:3',4'-d]phosphole derivatives as a new type of thiophene-fused phopholes. They exhibit the unique hybrid character of electron-withdrawing phosphole and electron-donating thiophene.
