| Outline of Final Research Achievements |
Toward alternate materials of fullerene derivatives in organic photovoltaics, a series of acceptor small molecules with arylene bisimide structure was synthesized by the typical Stille coupling reaction. Furthermore, the direct arylation synthesis of acceptor polymers with arylene bisimide structure was developed, which was the first accomplishment to sythesize those polymers under the direct arylation conditions. As for both small molecules and polymers, optoelectric properties and nano-morphology were controlled by tuning the structure. These results revealed the relationship between the molecular structure and molecular properties in arylane bisimide-based materials, which can be a guideline to design allternate acceptor materials of fullerene derivatives for organic photovoltaics.
