Success in obtaining higher‐order twistarenes with precise structures is very important for fundamentally understanding the relationship between the structures and physical properties/optoelectronic applications. In this research, by using the advantages from a retro‐Diels–Alder process (clean reaction) and the cross‐conjugated nature of the pyrene unit, a novel dodeca‐twistarene was prepared for the

芳烃对于从根本上了解结构与物理性质/光电应用之间的关系非常重要。在这项研究中,通过利用Diels-Alder逆反应(清洁反应)的优点以及the单元的交叉共轭性质,首次制备了新型
十二烷基-twistarene。通过单晶XRD分析证实其结构表明它具有扭曲角(≈30°),并且由于扭曲特性和强烈的分子间CH-π相互作用,晶格中的两个相邻分子彼此垂直。但是,其基本的理化特性表明其在空气中的不稳定性是由于其较高的HOMO能级引起的,
