제목 Synthesis and electrical properties of novel oligomer semiconductors for organic field-effect transistors (OFETs): asymmetrically end-capped acene-heteroacene conjugated oligomers
초록 Small molecule semiconductors are particularly profitable for electronic applications because they can be reliably synthesized with accurate molecular weight control without significant batch-to-batch variations. Additionally, small molecule semiconductors can potentially provide high-quality chain alignment. Novel small molecules composed of an aromatic phenylene-trithiophene and naphthalene-trithiophene conjugated core were synthesized and examined for their property in p-type OFET devices. The phenylene and naphthalene moieties were combined with a trithiophene to introduce torsional structures into the conjugated core and improve the solubility compared with the solubility of the quaterthiophene core containing molecule. Although phenylene-trithiophene and naphthalene-trithiophene containing molecules showed lower mobilities than quaterthiophene containing molecule, they showed more film uniformity caused by improved solubility.
