In this study, construction of supramolecular assemblies was performed based on dehydroannulenes, carbon-rich conjugated macrocycles, with substituents capable of hydrogen bonding. As a result, specific superstructures were obtained : they include a co-axially stacked one dimensional structure, polymorphic structures depending upon the assembly conditions, and unusual organogels. we revealed that they exhibit interesting thermal, photophysical, and electronic properties upon the superstructures. Furthermore, laser irradiation yielded carbon nanostructures form the organogels.

在这项研究中，超分子组合物的构建是基于脱氢环烯，富碳共轭大环，具有能够氢键的取代基。结果，得到了特殊的超结构：它们包括同轴堆叠的一维结构，取决于组装条件的多态结构，以及不寻常的有机凝胶。我们发现，它们在超结构上表现出了有趣的热、光物理和电子性质。此外，在激光照射下，有机凝胶形成了碳纳米结构。
