A -symmetric triarylamine-based macrocycle (i.e., hexaaza[1]paracyclophane), decorated with six lateral amide functions, is synthesized by a convergent and modular strategy. This macrocycle is shown to undergo supramolecular polymerization in -dichlorobenzene, and its nanotubular structure is elucidated by a combination of spectroscopy and microscopy techniques, together with X-ray scattering and molecular modeling. Upon sequential oxidation, a spectroelectrochemical analysis of the supramolecular polymer suggests an extended electronic delocalization of charge carriers both within the macrocycles (through bond) and between the macrocycles along the stacking direction (through space).
一种基于不对称三芳基胺的大环化合物（即六氮杂[1]对环芳烷），带有六个侧链酰胺官能团，通过一种收敛性和模块化策略合成。该大环化合物在对二氯苯中发生超分子聚合，其纳米管结构通过光谱学和显微镜技术的结合，以及X射线散射和分子建模得以阐明。经连续氧化后，对该超分子聚合物的光谱电化学分析表明，电荷载流子在大环化合物内部（通过化学键）以及沿着堆积方向在大环化合物之间（通过空间）都有扩展的电子离域。
