Abstract
Abstract 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.
