100mg |
Takimiya et al. have developed 2,7-diphenyl[1]benzothieno[3,2-b][1]benzothiophene (1) which includes chalcogen atoms in the molecule, and reported that it showed excellent properties as a semi-conductor. According to their results, the field-effect mobility of the thin film device using 1 is very high, and indicates a high value comparable as pentacene which has been researched actively as semiconductor. Moreover, it has high durability, and semiconducting properties were maintained for over 100 days.
