Recent development in the design and synthesis of organic semiconductors has been achieved great progress in the field of organic electronics. Among the various molecular building blocks, quinoidal molecules have attracted considerable interest as active materials for organic electronics, in particular, organic field-effect transistors (OFETs). Compared with common aromatic molecules, they have advantages such as highly planar structure and extended delocalization, which facilitates efficient π-π overlap between quinoidal backbones. Although quinoidal molecules exhibit many merits for organic electronics, organic semiconductors with well-defined quinoidal structure are still rare. In this study, we designed and synthesized novel type quinoidal organic semiconductors with different heterocyclic backbone in order to understand structure-property relationship. We investigated the properties of quinoidal semiconductors and fabricated OFET devices to estimate their electrical properties. |
