| Outline of Final Research Achievements |
Ａ new series of conjugated thienoacene derivatives has been developed. These molecules can self-organize into single-crystal microribbons or microsheets through simple solution processes, where attractive intermolecular S···S interactions induce closely packed molecular association. The well-defined single-crystal microribbons and microsheets have been applied to organic field-effect transistors. High carrier mobilities of up to 10.2 cm2/V s and high on/off ratios of about 10^7 have been achieved in organic field-effect transistors incorporating the single-crystal microribbons. We have thus demonstrated that by utilizing the thienoacene derivatives with unique self-organization abilities, excellent p-type semiconducting properties can be attained. These results provide an advanced design strategy for combination of molecular self-organization with materials fabrication to achieve desirable electro-functions for organic field-effect transistors.
