合成了一种新的给体分子3，8-二甲氧基-[1]苯并噻吩并[3，2-B][1]苯并噻吩（DMeO-BTBT），并与氟代7，7，8，8-四氰基醌二甲烷（F-n-TCNQ; n = 0，2，4）合成了电荷转移配合物。所有配合物（DMeO-BTBT）（F-n-TCNQ）具有混合堆叠结构，并且薄膜和单晶有机晶体管在真空和空气中即使在一年的储存后也显示出n沟道晶体管性能。虽然薄膜晶体管的性能和稳定性根据F-n-TCNQ的受体能力得到改善，但所有单晶晶体管都表现出相似的性能和优异的空气稳定性，其中（DMeO-BTBT）（F-2-TCNQ）晶体管表现出最高的迁移率，为0.097 cm（2）V-1 s（-1）。
A new donor molecule 3,8-dimethoxy-[1] benzothieno[3,2-b][1] benzothiophene ( DMeO-BTBT) is synthesized and the charge-transfer complexes with fluorinated 7,7,8,8-tetracyanoquinodimethane (F-n-TCNQ; n = 0, 2, and 4) are prepared. All complexes (DMeO-BTBT)(F-n-TCNQ) have mixed stack structures, and the thin-film and single-crystal organic transistors show n-channel transistor performance both in vacuum and in air even after one-year storage. Although the performance and stability of the thin-film transistors are improved according to the acceptor ability of F-n-TCNQ, all single-crystal transistors exhibit similar performance and excellent air stability, among which the (DMeO-BTBT)(F-2-TCNQ) transistor exhibits the highest mobility of 0.097 cm(2) V-1 s(-1).
