A polymer consisting of a polynorbornene backbone with perylene diimide (PDI) pendant groups on each monomeric unit is synthesized via ring opening metathesis polymerization. The PDI pendant groups along the polymer backbone, studied by UV–vis absorption, fluorescence emission, and electron paramagnetic resonance spectroscopy in addition to electrochemical methods, show evidence of molecular aggregation and corresponding electronic coupling with neighboring groups, which forms pathways for efficient electron transport from one group to another in a specific reduced form. When n‐doped, the title polymer shows redox conductivity of 5.4 × 10⁻³ S cm⁻¹, comparable with crystalline PDI materials, and is therefore a promising material for use in organic electronics.

聚降冰片烯链上的n掺杂Per二酰亚胺基团的电子相互作用：对有机电子中电子传输的影响

经由开环易位聚合，合成由在每个单体单元上具有per二酰亚胺（PDI）侧基的聚降冰片烯主链组成的聚合物。除电化学方法外，还通过紫外可见吸收，荧光发射和电子顺磁共振波谱研究了沿聚合物主链的PDI侧基，这些分子显示出分子聚集和与邻近基团的相应电子偶联的证据，这形成了有效的电子传输途径从一组到另一组以特定的简化形式出现。n掺杂时，标题聚合物的氧化还原电导率为5.4×10 ^-3 S cm ^-1，与结晶PDI材料相当，因此是用于有机电子领域的有前途的材料。
