We have synthesized two novel organic semiconductors, which have a symmetrically substituted 2,7-divinyl[1]benzothieno[3,2-b]benzothiophene backbone. They show good electrical performances on a SiO2/Si substrate, with high field-effect mobilities of up to 0.4 cm2V−1 s−1, and can easily be synthesized in large quantities. In addition, there is no significant change in the mobility of DPV-BTBT even after the device is exposed to air for at least 60 days (further monitoring is in progress), showing that it is a promising air-stable p-channel organic semiconductor that can be applied to all-organic flexible electronic devices.
我们合成了两种新型有机半导体,它们具有对称取代的 2,7- 二乙烯基[1]苯并噻吩并[3,2-b]苯并噻吩骨架。它们在二氧化硅/硅衬底上显示出良好的电性能,场效应迁移率高达 0.4 cm2V-1 s-1,而且很容易大量合成。此外,DPV-BTBT 器件在空气中暴露至少 60 天后,其迁移率也没有发生明显变化(正在进一步监测中),这表明它是一种具有良好空气稳定性的 p 沟道有机半导体,可应用于全有机柔性电子器件。
