共价桥联柱芳烃低聚物（CBPO）是由柱芳烃单体共价键合形成的，由于其优异的分子络合能力、特殊设计的几何形状和多功能连接基团，在扩展柱芳烃的多学科应用方面发挥着关键作用。本文对 CBPO 的合成和应用进行了全面的综述。首先介绍了一系列CBPO（二聚体、三聚体、四聚体等）的设计和合成策略。许多具有多腔和独特几何形状的CBPO是非常有吸引力和有效的构建模块，可用于通过主客体相互作用构建具有不同拓扑结构的新型智能超分子聚合物（SP）。我们详细描述了基于 CBPO 构建各种 SP 的方法。此外，系统介绍了CBPO和基于CBPO的SP在离子和有机小分子的识别与检测、选择性吸附与分离、人工光捕获系统、催化、药物递送系统等方面的广泛应用。最后，还强调了 CBPO 未来的挑战和前景。
Covalently bridged pillararene-based oligomers (CBPOs) are formed by covalent bonding of pillararene monomers, and they play a critical role in expanding the multi-disciplinary application of pillararenes due to their excellent molecular complexing ability, specially designed geometry and multifunctional linking groups. This article provides a comprehensive review of the synthesis and applications of CBPOs. The design and synthetic strategies of a series of CBPOs (dimers, trimers, tetramers and others) are first introduced. Many CBPOs with multi-cavities and unique geometry are very attractive and efficient building blocks for constructing novel smart supramolecular polymers (SPs) with different topological structures through host-guest interactions. We describe the methods of constructing various SPs based on CBPOs in detail. Furthermore, the extensive applications of CBPOs and CBPO-based SPs in recognition and detection of ions and organic small molecules, selective adsorption and separation, artificial light-harvesting systems, catalysis, drug delivery systems, and others are systematically introduced. Finally, the future challenges and perspectives for CBPOs are also highlighted.
