  Novel Thiophene–Phenylene–Thiophene Fused Bislactam-Based Donor–Acceptor Type Conjugate Polymers: Synthesis by Direct Arylation and Properties

  摘要：

  Three new donor acceptor copolymers based on thiophene phenylene thiophene fused bislactam and various donors (3,4-dodecylthiophene, 4,4'-didodecyl-2,2'-bithiophene, and ethylenedioxythiophene) were synthesized, characterized, and used in field-effect transistors. Polycondensation was performed using nonactivated thiophene derivatives by employing palladium-catalyzed direct arylation under phosphine-free conditions. This method is superior to traditional cross-coupling polymerization because it requires fewer synthetic operations and does not employ toxic organometallic intermediates. Regioselective polymers can also be generated by using beta-substituted thiophene derivatives. The studied polymers were tested in a bottom gate top contact thin film transistor (OTFT) architecture. The best electronic performance was shown by polymer P3, with enhanced pi-conjugation due to the appearance of intramolecular attractive interactions.

  Five π‐extended lactam‐fused conjugated oligomers (5FO, 5FS, 4FPO, 4FPS, and R‐4FPO) were synthesized by the tandem direct arylation. The intermolecular oxidative direct arylation was applied in the second step. These conjugated oligomers had fine‐tuned FMO energies predictable by the theoretical calculation and excellent thermal stabilities. 4FPO and 4FPS bearing tetrafluoropyridine exhibited lower

  通过串联直接芳基化反应合成了五个π延伸的内酰胺融合共轭低聚物（5FO，5FS，4FPO，4FPS和R-4FPO）。在第二步骤中应用分子间氧化直接芳基化。这些共轭低聚物具有可通过理论计算预测的FMO能量微调，并且具有出色的热稳定性。与其他相比，带有四氟吡啶的4FPO和4FPS表现出较低的LUMO能级（分别为-3.20 eV和-3.39 eV）。基于X射线晶体学，4FPO被发现具有人字形晶体堆积和相当大的电子转移积分值（137 meV）。基于4FPO的底栅，底接触FET器件由于在SiO 2衬底上进行边沿对准而显示出5.2×10 -3  cm 2  V -1  s -1的电子迁移率。
