Polycyclic aromatic hydrocarbons with zigzag peripheries are high perspective candidates for organic electronics. However, large fused acenes are still poorly studied due to the tedious synthesis. Herein we report a non-substituted fused bistetracene DBATT (2.3,8.9-dibenzanthanthrene) as the semiconductor on low-voltage-driven organic thin-film transistors. The systematic studies of thin-film growth on various self-assembled monolayer (SAM) modified gate dielectrics and the electrical performances were carried out. The sub-monolayer of the semiconductor film shows larger island domains on the alkyl chain SAM. This device exhibits the hole mobility of 0.011 cm²·V⁻¹·s⁻¹ with a current ratio of I_onII_off above 10⁵.

具有锯齿形周边的多环芳烃是有机电子领域的高前景候选者。但是，由于繁琐的合成，对大型并苯并苯的研究仍然很少。在本文中，我们报告了一种非取代的熔融双硬脂酰胺DBATT（2.3,8.9-dibenzanthanthrene）作为低压驱动有机薄膜晶体管上的半导体。对各种自组装单层（SAM）改性栅极电介质上的薄膜生长和电性能进行了系统的研究。半导体膜的亚单层在烷基链SAM上显示出较大的岛结构域。该器件在电流比为I _on II _off时表现出0.011 cm ² ·V ^-1 ·s ^-1的空穴迁移率10以上⁵。
