以5，5 ′-双联苯二噻吩并[3，2-B：2′，3 ′-d]噻吩（BPDTT）为半导体层，聚乙烯醇（PVA）为栅介质层，制备了有机薄膜晶体管。这些器件表现出优异的场效应性能，在室温下具有高达0.6cm 2 scinVs的高迁移率和非常低的工作电压（<1V）。生长并分析了BPDTT的单晶。BPDTT分子间的紧密人字形堆积和PVA与BPDTT分子间的高度均匀性是其高性能的主要原因。
Employing 5,5′-bis-biphenyl-dithieno[3,2-b:2′,3′-d]thiophene (BPDTT) as semiconducting layer and poly(vinyl alcohol) (PVA) as gate dielectric layer, we have fabricated organic thin-film transistors. These devices exhibit excellent field-effect performances with a high mobility of up to 0.6cm2∕Vs and a very low operating voltage (<1V) at room temperature. The single crystal of BPDTT was grown and analyzed. The high performances are mainly attributed to the close herringbone packing of BPDTT molecules and the high homogeneity between PVA and BPDTT molecules.
