Outline of Final Research Achievements

Organic field-effect transistors have been paid much attention due to the low-cost and environment friendly solution processability and flexibility. However, there are still requirements of materials which possess high carrier mobility, sufficient solubility for solution process, and chemical and thermal stability. In this research, W-shaped organic semiconducting materials were newly developed to control the molecular orbital and aggregation structures. X-ray single crystal analyses and calculation of transfer integrals suggest their high potential utility. Indeed, these materials exhibited high performance by use of single crystal thin film prepared by solution process.
