Several bisacenaphthopyrazinoquinoxaline (BAPQ) based derivatives 1–3 were synthesized by condensation between the acenaphthenequinones and 1,2,4,5-tetraaminobenzene tetrahydrochloride. Their optical, electrochemical and self-assembling properties are tuned by different substituents. Among them, compound 3 possesses a homogeneously distributed low-lying LUMO due to the peripheral substitution with four cyano groups. The corresponding n-channel field effect transistors showed a field effect electron mobility of 5 × 10−3 cm2 V−1 s−1.
通过苊醌与 1,2,4,5- 四氨基苯四盐酸盐的缩合,合成了几种基于双萘并吡嗪喹喔啉(BAPQ)的衍生物 1-3。不同的取代基调节了它们的光学、电化学和自组装特性。其中,化合物 3 由于外围取代了四个氰基,因此具有均匀分布的低洼 LUMO。相应的 n 沟道场效应晶体管显示出 5 × 10-3 cm2 V-1 s-1 的场效应电子迁移率。
