  Low-Voltage Organic Transistors Based on Tetraceno[2,3-b]thiophene: Contact Resistance and Air Stability

  摘要：

  The small-molecule organic semiconductor tetraceno[2,3-b]thiophene has been synthesized through an environmentally friendly synthetic route, utilizing NaBH4, rather than Al/HgCl2, for the reduction of the quinone. Low-voltage organic thin-film transistors (TFTs) have been fabricated using tetraceno[2,3-b]thiophene and, for comparison, pentacene and anthradithiophene as the semiconductor. The tetraceno[2,3-b]thiophene TFTs have an effective field-effect mobility as large as 0.55 cm(2) V-1 s(-1) and a subthreshold swing of 0.13 V/decade. In addition, it has been found that the contact resistance of the tetraceno[2,3-b]thiophene TFTs is substantially smaller than that of the anthradithiophene TFTs and similar to that of the pentacene TFTs. The long-term air stability of TFTs based on all three semiconductors has been monitored over a period of 12 months. The initial charge-carrier mobility of the tetraceno[2,3-b]thiophene TFTs is similar to 50% smaller than that of the pentacene TFTs, but as a result of the greater ionization potential and better air stability induced by the terminal thiophene ring condensed at the thiophene-b-bond, the tetraceno[2,3-b]thiophene TFTs outperform the pentacene TFTs after continuous exposure to ambient air for just 3 months.

  understanding of the electronic properties at the individual molecular level and the development of methods to tune the charge transport through molecular junctions. Scanning tunneling microscopy (STM) is an ideal tool not only for the characterization, but also for the manipulation of single atoms and molecules on surfaces. The conductance through a single molecule can be measured by contacting the molecule

  进步基于单分子电子设备的先决条件是更好地理解单个分子水平上的电子性质以及调节通过分子结的电荷传输的方法的发展。扫描隧道显微镜（STM）不仅是表征的理想工具，而且还是处理表面上单个原子和分子的理想工具。通过使单个分子以原子精度接触并在金属STM尖端电极和金属表面电极之间形成分子桥，可以测量通过单个分子的电导。影响电导的参数主要与它们的电子结构以及与金属电极的耦合有关。这里，实验和理论分析着重于单四噻吩噻吩分子，并证明了噻吩部分的原位诱导直接脱硫反应通过在分子碳和铜表面原子之间形成共价键而大大改善了分子锚定。与初始状态相比，该键形成导致电导增加约50％。

  Attempts to functionalize polycyclic quinones using lithium diisopropylamide as a base led to the unexpected formation of acenes. This reaction proceeds by electron transfer from the base to the electron deficient quinone, whose radical anion can react with a variety of electrophiles. Siloxy derivatives synthesized by this method could be easily isolated but showed poor photostability. In situ reduced

Reductive alkylation of quinone precursors yielded target dialkoxyacenes with fused backbones ranging from benzodithiophene to tetracenothiophene.
