为了创造下一代有机电子材料，π系统的集成最近已成为一个中心主题。当芳香族π-体系作为单体时，这种功能材料可以通过超分子聚合来组装，所得到的超分子聚合物的性质强烈地依赖于单体的电子结构。在这里，我们展示了一种以抗芳香族π-体系为单体的超分子聚合物的构建。通过π-π堆积和氢键作用，酰胺功能化的NiI-Inorcorro衍生物形成了一维超分子聚合物，确保了传导路径的持久性，使其在紧密结合的线性聚集体上的电荷迁移率高于由锌卟啉组成的芳香族类似物。
For the creation of next‐generation organic electronic materials, the integration of π‐systems has recently become a central theme. Such functional materials can be assembled by supramolecular polymerization when aromatic π‐systems are used as monomers, and the properties of the resulting supramolecular polymer strongly depend on the electronic structure of the monomers. Here, we demonstrate the construction of a supramolecular polymer consisting of an antiaromatic π‐system as the monomer. An amide‐functionalized NiIInorcorrole derivative formed a one‐dimensional supramolecular polymer through π‐π stacking and hydrogen‐bonding interactions, ensuring the persistency of the conducting pathway against thermal perturbation, which results in higher charge mobility along the tightly bound linear aggregates than that of the aromatic analogue composed of ZnIIporphyrins.
