title: Donor-acceptor-donor type organic semiconductor containing quinoidal benzo[1,2-b:4,5-b']dithiophene for high performance n-channel field-effect transistors.
abstract: A donor-acceptor-donor (D-A-D) type small molecule , with dicyano-substituted quinoidal benzo[1,2-b:4,5-b']dithiophene as the acceptor, was designed and synthesized. A high electron mobility up to 0.88 cm(2) V(-1) s(-1) was observed for based transistors under ambient conditions, suggesting quinoidal benzo[1,2-b:4,5-b']dithiophene is an excellent acceptor unit in D-A type n-channel organic semiconductors.
