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-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 IonIIoff above 105.
