冠醚和环糊精等环状和管状分子自被发现以来就在超分子化学中发挥着重要作用。迄今为止，许多有趣的性质和反应性已被报道基于其独特的内部微环境。虽然被脂肪族和/或小芳族框架包围的内部空间已经被大量研究，但直到2010年，以聚芳族框架为特征的管状结构仍然在很大程度上未被探索，尽管它们具有无可争议的潜力。聚芳环提供了吸引人的物理和电化学性质，从而允许构建新的功能性圆柱形纳米空间。这篇专题文章介绍了带有多个（3）聚芳环的短管状分子（例如，蒽、芘、芘和HBC）。本文报道的聚芳族管显示出特征性质，如强荧光发射、选择性分子结合能力、有效的主客体能量转移和开闭结构转变。
Ring- and tube-shaped molecules like crown ethers and cyclodextrins play a fundamental role in supramolecular chemistry since their initial discovery. To date, numerous intriguing properties and reactivities have been reported based on their unique inner microenvironments. While inner spaces encircled by aliphatic and/or small aromatic frameworks have been heavily investigated, tubular structures that feature polyaromatic frameworks remained largely unexplored until 2010, despite their undisputable potential. Polyaromatic rings provide appealing photophysical and electrochemical properties and thus allow for the construction of new functional cylindrical nanospaces. This feature article describes the recent progress in the synthesis and application of short tubular molecules bearing multiple (3) polyaromatic rings (e.g., anthracene, pyrene, chrysene, and HBC). The polyaromatic tubes reported herein display characteristic properties such as strong fluorescent emission, a selective molecular binding ability, efficient host-guest energy transfer and open-closed structural transformations.
