Despite the fact that pillar[n]arenes receive major interest as building blocks for supramolecular chemistry and advanced materials, their functionalization is generally limited to the modification of the hydroxy or alkoxy units present on the rims. This limited structural freedom restricts further developments and has very recently been overcome. In this article, we highlight three very recent studies demonstrating further structural diversification of pillar[n]arenes by partial removal of the alkoxy substituents on the rims, which can be considered as the next generation of pillar[n]arenes.
尽管柱芳烃作为超分子化学和先进材料的构建单元备受关注，但其功能化通常仅限于对其边缘存在的羟基或烷氧基单元进行修饰。这种有限的结构自由度限制了进一步的发展，而这一限制最近已被克服。在本文中，我们重点介绍了三项最新研究，这些研究通过部分去除边缘的烷氧基取代基展示了柱芳烃进一步的结构多样化，这可被视为下一代柱芳烃。
