| Outline of Final Research Achievements |
New benzothienobenzothiophene (BTBT) derivatives tailored by incorporating two adjacent substituent groups having hydrogen-bonding ability at the 2,3- and 2,3,7,8-positions have been synthesized. The methoxy-substituted BTBT derivatives form a lamellar herringbone packing structure in the crystal, while the thin-film morphologies of each derivatives depend on the side-chain effect of the introduced methoxy groups and strongly influence the transistor properties.
In addition, the hydroxy-substituted BTBT derivative produces a charge-transfer salt, in which the introduced hydroxy groups form a hydrogen-bonded chain structure with counter anions. This unique structural feature effectively increases the dimensionality of the electronic structure, leading to the stabilization of metallic conducting behavior.
