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 S cm , comparable with crystalline PDI materials, and is therefore a promising material for use in organic electronics.
通过开环易位聚合合成了一种由聚降冰片烯主链和每个单体单元上的苝二酰亚胺（PDI）侧基组成的聚合物。PDI 侧基沿聚合物主链，通过紫外-可见吸收、荧光发射和电子顺磁共振光谱以及电化学方法进行研究，表明存在分子聚集的证据，并与相邻基团发生相应的电子耦合，这为特定还原形式下电子从一个基团到另一个基团的有效传输形成了途径。当 n 掺杂时，该聚合物表现出 5.4×10 S cm 的氧化还原电导率，与结晶 PDI 材料相当，因此是用于有机电子学的有前途的材料。
