An effective method was developed to prepare triphenyleno[1,2,3,4-ghi]perylenediimide derivatives, via ICl-induced annulation, dehalogenation, followed by photocyclization. A perylenediimide (PDI) dimer featuring a terphenyl bisethynylene linker was thereby transformed into a benzo[k]tetraphene fused with two benzoperylenediimides. These PDI derivatives exhibited electron mobility up to 0.079 cm2 V−1 s−1 in solution-processed thin film transistors.
通过 ICl 诱导的环化、脱卤和光环化,开发出了一种制备三苯基烯并[1,2,3,4-ghi]过二亚胺衍生物的有效方法。以三联苯二乙炔连接体为特征的过乙二亚胺(PDI)二聚体由此转化为与两个苯并过乙二亚胺融合的苯并[k]四烯。这些 PDI 衍生物在溶液加工的薄膜晶体管中显示出高达 0.079 cm2 V-1 s-1 的电子迁移率。
