A set of three core-cyanated isoindigos was synthesized by palladium-catalyzed cyanation of core-brominated isoindigos. With decreased LUMO level to -3.88 eV, the dicyanated isoindigo 5 showed ambient-stable electron mobility up to 0.044 cm(2) V(-1) s(-1) in OTFTs with SAMs of TPA, while it exhibited ambipolar charge transport behaviour (0.11 cm(2) V(-1) s(-1) for electrons and 0.045 cm(2) V(-1) s(-1) for holes) on FOPA-modified substrates.
一套三种核心氰化异吲哚的合成是通过钯催化的核心溴化异吲哚的氰化反应得到的。由于 LUMO 能级降低到-3.88 eV,二氰化异吲哚 5 在具有 TPA SAMs 的 OTFT 中表现出环境稳定的电子迁移率,高达 0.044 cm(2) V(-1) s(-1),而在 FOPA 改性衬底上则表现出双极电荷输运行为(电子为 0.11 cm(2) V(-1) s(-1),空穴为 0.045 cm(2) V(-1) s(-1))。
