Development of Ambipolar Organic Semiconducting Materials by Utilizing Microphase Separation

合成了低聚硫杂二聚体，并将其应用于双极性有机半导体。杂二聚体包括作为空穴传输单元的低聚硫吩基，作为电子传输单元的羰基取代的低聚硫吩基，以及在两端用于微相分离的两个取代基。此外，我们还合成了多种苯和杂环线性熔合的杂苯化合物，并将其应用于有机场效应晶体管中。

Oligothiophene heterodimers were synthesized to apply as ambipolar organic semiconductors. The heterodimers consist of an oligothiophene moiety as hole transport unit, a carbonyl-substituted oligothiophene moiety as electron transport unit, and two substituents at the both terminals for microphase separation. In addition, a variety of heteroacenes, where benzene and heterocycle rings are fused linearly, were synthesized and applied to organic field-effect transistor.
