Three new organic semiconductors with alkyl chain-substituted tetrathienoacene (TTAR) as the central core and both ends capped with thiophene (DT-TTAR), thienothiophene (DTT-TTAR) and dithienothiophene (DDTT-TTAR) have been synthesized and characterized for organic field effect transistor (OFET) applications. A hole mobility of 0.81 cm V s was achieved for the DDTT-TTAR film, which represents the highest mobility yet found for a solution-processable p-type TTAR-based small molecular semiconductors.
合成了三种以烷基链取代的四硫并并四苯（TTAR）为中心核且两端分别被噻吩（DT-TTAR）、噻吩并噻吩（DTT-TTAR）和二噻吩并噻吩（DDTT-TTAR）封端的新型有机半导体，并对其进行了表征，以用于有机场效应晶体管（OFET）应用。DDTT-TTAR薄膜实现了0.81 cm² V⁻¹ s⁻¹的空穴迁移率，这代表了可溶液加工的基于p型TTAR的小分子半导体迄今发现的最高迁移率。
