Abstract:	摘要： AbstractThree new benzothieno[3,2‐b]thiophene (BTT; 1) derivatives, which were end‐functionalized with phenyl (BTT‐P; 2), benzothiophenyl (BTT‐BT; 3), and benzothieno[3,2‐b]thiophenyl groups (BBTT; 4; dimer of 1), were synthesized and characterized in organic thin‐film transistors (OTFTs). A new and improved synthetic method for BTTs was developed, which enabled the efficient realization of new BTT‐based semiconductors. The crystal structure of BBTT was determined by single‐crystal X‐ray diffraction. Within this family, BBTT, which had the largest conjugation of the BTT derivatives in this study, exhibited the highest p‐channel characteristic, with a carrier mobility as high as 0.22 cm2 V−1 s−1 and a current on/off ratio of 1×107, as well as good ambient stability for bottom‐contact/bottom‐gate OTFT devices. The device characteristics were correlated with the film morphologies and microstructures of the corresponding compounds. 其他題名： Chem. Eur.
