Organic perylene diimide-based compounds are provided. Methods of producing the organic compounds is also provided as well as methods of their use including, among other things, their use as organic semiconductor materials.
design and synthesis of a new graphene ribbon architecture that consists of perylenediimide (PDI) subunits fused together by ethylene bridges. We created a prototype series of oligomers consisting of the dimer, trimer, and tetramer. The steric congestion at the fusion point between the PDI units creates helical junctions, and longer oligomers form helical ribbons. Thin films of these oligomers form the
我们描述了一种新的石墨烯带结构的设计和合成,该结构由通过乙烯桥融合在一起的苝二亚胺 (PDI) 亚基组成。我们创建了由二聚体、三聚体和四聚体组成的低聚物原型系列。PDI 单元之间融合点的空间拥挤产生螺旋连接,较长的低聚物形成螺旋带。这些低聚物的薄膜形成 n 型场效应晶体管中的有源层。UV-vis 光谱揭示了四聚体中强烈的长波长跃迁的出现。从 DFT 计算,我们发现四聚体中 HOMO-2 到 LUMO 的跃迁与 HOMO 到 LUMO 的跃迁是等能的。我们使用飞秒瞬态吸收光谱直接探测这些跃迁。

A rylene annulated phthalocyanine was designed with a quasi-planar “four leaf clover” skeleton and a two-dimensional cage-like supramolecular structure.
and molecular weight on the absorption, electrochemistry, thermalstability, and photovoltaic application of polymers were studied. Pure 1,7-DBPDIs lead to polymers with molecular weight distribution as low as 1.08. These polymers with strong absorption in 300–700 nm, low-lying lowest unoccupied molecular orbital (LUMO) energy levels around −4.0 eV and highthermalstability could be excellent electron
