Organic semiconductors with high mobility and high thermal stability are of great importance for practical application of organic electronics. To explore new semiconductors by taking advantage of the intrinsic properties of tetracene molecule, herein, we report the design and synthesis of a novel p-type tetracene derivatives, 2-(anthracen-2-yl)tetracene (TetAnt). Top contact organic thin-film transistors (OTFTs) based on TetAnt show a hole mobility of up to 0.79 cm² V⁻¹ s⁻¹. In addition, a high mobility of ~0.4 cm² V⁻¹ s⁻¹ is maintained even after thermal stressed to a high temperature of 290 °C, indicating the excellent thermal stability of TetAnt.

具有高迁移率和高热稳定性的有机半导体对于有机电子的实际应用非常重要。为了利用并四苯分子的固有特性探索新的半导体，我们在此报告了新型p型并四苯衍生物2-（蒽-2-基）并四苯（TetAnt）的设计和合成。基于TetAnt的顶部接触有机薄膜晶体管（OTFT）显示出最高0.79 cm ²  V ^-1  s ^-1的空穴迁移率。另外，即使在热应力至290℃的高温后也保持〜0.4cm ²  V ^-1  s ^-1的高迁移率，表明TetAnt的优异的热稳定性。
