摘要

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-voltagedriven 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 0.011cm2·V-1 ·s-1 with a current ratio of/on//off above 105.
