| Abstract: | A novel S-containing heteroacene,i.e.3-undecylbenzothieno3,2-b;4,5-b′] dithiophene(BTTT),was synthesized.Four conjugated oligomers which comprise BTTT as the terminal units and thiophene(T),bithiophene(bT),N-dodecyl-dithieno3,2-b:2′3′-d]pyrrole(TP) or 2,5-bis(3-dodecylthiophen-2-yl)thieno thiophene(qT) as the central unit,respectively,were prepared and characterized.The HOMO energy levels and optical bandgaps of the conjugated oligomers varied in the range of-5.35~-4.95 eV and 2.62~2.44 eV,respectively.Ordered films can be prepared by solution casting from all oligomers.Except for T-BTTT,bT-BTTT,TP-BTTT and qT-BTTT all showed a lamellar molecular arrangement in film.Organic thin film transistors(OTFTs) with bottom gate and top contact device structure were prepared.qT-BTTT displays the best device performance with a field-effect mobility(μFET) up to 0.012 cm2/V·s. |
