Novel sulfur-containing aromatic compounds were developed as stable, high-performance organic semiconductors for OTFT applications. Of them, dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT) consisting of six aromatic rings gave high quality thin films by vapor deposition, which acted as a superior FET channel showing FET mobility as high as 3.0 cm2V -1s-1. On the other hand, highly soluble 2,7-dialkylbenzothieno[3,2-b]benzothiophenes (Cn-BTBTs) gave solution-processible OTFTs with FET mobility higher than 1.0 cm 2V-1s-1.
