Fluoro-substituted phenyleneethynylenes are synthesized by Sonogashira coupling and acetylide-nucleophilic substitution of fluorobenzenes. Fluoro-substitution of benzenes enables deep LUMO potential, and CF3-substitution provides high electron mobility in deposited film (μ = 5.5 × 10−2 cm2 V−1 s−1).
氟取代的亚苯基乙炔基是通过 Sonogashira 偶联和氟苯的乙炔亲核取代合成的。苯的氟取代可实现深 LUMO 电势,CF3 取代可在沉积薄膜中提供高电子迁移率 (μ = 5.5 × 10−2 cm2 V−1 s−1)。
